COLLEGE PARK, Md. — The highly anticipated quantum science-based revolution in information technology requires the development of groundbreaking hardware comparable in function to the transistors used in today’s computers. Researchers at the University of Maryland’s A. James Clark School of Engineering and Joint Quantum Institute (JQI) have cleared a hurdle in the development of such quantum-compatible hardware with their demonstration of the first single-photon transistor using a semiconductor chip. 

Transistors are tiny switches that are the foundation of modern computing. Billions of them route electrical signals around inside the computers that power our smartphones, tablets and other devices. Quantum computers will need analogous hardware to manipulate quantum information. But the design constraints for this new information technology are stringent, and today’s most advanced processors can’t be repurposed as quantum devices. That’s because quantum information carriers, dubbed qubits, have to follow the radically different rules laid out by quantum physics. 

Scientists can use many kinds of quantum particles as qubits, even the photons that make up light. Photons have added appeal because they can swiftly shuttle information over long distances, and they are compatible with fabricated chips. However, making a quantum transistor triggered by light has been challenging because it requires that the photons interact with each other, something that doesn’t ordinarily happen. 

The Maryland research team headed by Professor of Electrical and Computer Engineering, JQI Fellow, and Institute for Research in Electronics and Applied Physics Affiliate Edo Waks—has used a quantum memory to make photons interact, creating the first single-photon transistor made from a semiconductor.  

The device has numerous holes in it, making it appear much like a honeycomb. Light entering the chip bounces around and gets trapped by the hole pattern. A small crystal sits inside the area where the light intensity is strongest, and, analogous to conventional computer memory, this crystal stores information about photons as they enter the device. It can then effectively tap into that memory to mediate interactions with other photons that later arrive at the chip.

The team observed that a single photon could, by interacting with the crystal, control the transmission of a second light pulse through the device. The first light pulse acts like a key, opening the door for the second photon to enter the chip. If the first pulse didn’t contain any photons, the crystal blocked subsequent photons from getting through. This behavior is similar to a conventional transistor where a small voltage controls the passage of current through its terminals. Here, the researchers successfully replaced the voltage with a single photon and demonstrated that their quantum transistor could switch a light pulse containing around 30 photons before the device’s memory ran out.

“Using our transistor, we should be able to perform quantum gates between photons,” says Waks. “Software running on a quantum computer would use a series of such operations to attain exponential speedup for certain computational problems.

Their device, described in the July 6 issue of Science, is compact; roughly one million of these new transistors could fit inside a single grain of salt. It is also fast and able to process 10 billion photonic qubits every second.

With realistic engineering improvements their approach could allow many quantum light transistors to be linked together, according to lead author Shuo Sun, a postdoctoral research fellow at Stanford University who was a UMD grad student at the time of the research. The team hopes that such speedy, highly connected devices will eventually lead to compact quantum computers that process large numbers of photonic qubits, .

The University of Maryland (UMD) is home to one of the world’s top quantum science and technology communities, with over 200 quantum researchers on-site. UMD’s quantum science & tech partnerships and startups include:

  • the Joint Quantum Institute, (UMD the National Institute of Standards and Technology), is based on UMD’s campus and dedicated to the broad study of quantum science from theory to experiment;
  • the Joint Center for Quantum Information and Computer Science (QuICS) is a UMD-NIST initiative working to understand and enable the full promise of quantum computation, including providing quantum software to go with the quantum hardware;
  • the U.S. Army Research Laboratory Center for Distributed Quantum Information—primary academic partners, the University of Maryland, University of Chicago, University of Wisconsin, and University of Innsbruck—is developing quantum communication capabilities based on interfaces between quantum memory and photons;
  • IonQ, a quantum computing startup co-founded by UMD/JQI quantum scientist Christopher Monroe, UMD Bice Zorn Professor of Physics and Distinguished University Professor. Monroe also has played a leading role in creating the blueprint for a National Quantum Initiative

This work was supported by the Physics Frontier Center at the Joint Quantum Institute, the National Science Foundation, and the U.S. Army Research Laboratory Center for Distributed Quantum Information.

To Nap or Not? UMD Researcher Studies Impact of Sleep on Memory in Pre-Schoolers

July 2, 2018

COLLEGE PARK, Md.-- While many parents hope their children continue to take daily naps for as long as possible, new University of Maryland-led research aims to determine just how important napping is during the formative preschool years. The National Institutes of Health and the National Science Foundation awarded researchers more than $1 million to examine the role of sleep on brain development and memory in children ages 3 to 5, when they typically begin transitioning out of naps. 

Napping child“Although research shows naps clearly benefit learning and memory in young children, it’s still unclear why naps are important and how they are related to development of memory-related brain structures,” explained Tracy Riggins, an Associate Professor of Psychology at UMD who is leading the study. “There is somewhat of a debate regarding whether naps should be encouraged in preschool or eliminated to provide more time for early learning. Currently, there are no formal recommendations from organizations like the American Academy of Pediatrics, but we hope our research will help provide the basis for more informed decisions regarding naps for parents, educators and doctors in the future.”

Riggins, in collaboration with Rebecca Spencer, an Associate Professor of Psychology at the University of Massachusetts Amherst, will study whether the hippocampus—a part of the brain critical for formation of new memories—can retain more information as a child matures, reducing the need for periods of memory consolidation during sleep. 

For their study, researchers plan to recruit 100 4-year-olds, some of whom are non-nappers and some of whom are habitual nappers. They will observe the children napping or remaining awake during their normal naptimes in their homes. The research team will record brainwaves and muscle activity during naps to assess sleep quality and will ask the children to participate in memory games such as remembering pictures and stories. Children will also visit the University of Maryland for an MRI brain scan, which will allow researchers to examine memory-related brain structures, like the hippocampus, known to be critical for memory in adults. 

“Our study will be the first to combine measures of memory ability, sleep physiology and brain development in preschool children,” Riggins said. “Ultimately, we hope to better understand how sleep—napping, specifically—may be related to improvements in memory and the maturation of memory-related brain circuitry during these important early childhood years, when a child is learning and growing at an astonishing pace.” 

The researchers plan to follow the participants for one year in order to track changes in each child’s memory, nap status and brain development.  Parents with preschoolers who may be interested in participating should contact Dr. Riggins’ lab at KidBrainStudy@umd.edu for more information.

Evans has played a key role in operations, fundraising and Terrapin student-athlete success since 2014 

Damon EvansCOLLEGE PARK, Md. - The University of Maryland has named Damon Evans as Athletic Director of the Maryland Terrapins. Evans, who joined the university in December 2014 and most recently served as Executive Athletic Director and Chief Financial Officer, has led the Terrapins to excel both on and off the field.

“Throughout his tenure here, Damon has demonstrated visionary, transparent, compassionate and ethical leadership,” said University of Maryland President Wallace D. Loh. “The candidates invited for interviews had impressive credentials and accomplishments. In the end, a senior leadership search is not only about capabilities. It is also about institutional fit and interpersonal trust and chemistry. In Damon, the University​ of Maryland​ has the right person at the right time.”

Evans, who has served as Executive Athletic Director since 2016 and Acting Athletic Director since April 2018, overseeing all day-to-day operations of the athletics department. 

“It is a great honor to be chosen to lead at the University of Maryland,” said newly appointed Director of Athletics Damon Evans. “Since the day I arrived, I have been inspired by the student-athletes, coaches and support team that strive for success in Maryland Athletics, and I look forward to many successes ahead in our Big Ten era. I’m guided by the principle that we learn from our wins and losses, and I am eager to lead an athletics department that ultimately achieves greatness together.”

Over the past four years, Damon revamped the athletics budget and financial operations, resulting in an operating surplus. Evans was appointed as the liaison to lead the new Cole Field House project, a bold facility that will unite vital programs in sports medicine, public health, athletics training and academic innovation. Additionally, he was the driving force behind the department's new multimedia rights agreement with the Washington, DC and Baltimore media markets that increased the department’s revenue by more than $30 million.

During Evans’ tenure overseeing day-to-day operations of the athletics department, the Terrapins have had three teams advance to the Final Four and have secured three Big Ten Championships. In that time, the Terrapins have also boasted 26 All-American student-athletes, eight Big Ten Players of the Year, three Big Ten Coaches of the Year and 42 All-Big Ten Honorees. 

Evans has shown his commitment to the academic success of Maryland student-athletes, strengthening the relationship between the athletics department and the academic units of the university. Evans notably oversaw a $21.25 million gift from Barry and Mary Gossett to establish an innovative, three-part support model for the academic success of student-athletes, the Barry and Mary Gossett Center for Academic and Personal Excellence. While Evans has led at Maryland, Terrapin student-athletes have had 151 All-Big Ten Academic Honorees, and nine programs earned perfect single-year Academic Progress Rates, while the football team turned in its best score (.981) since 2003.

Prior to Maryland, Evans served as the director of athletics at the University of Georgia from 2004-10, where he managed a program with 600 student-athletes, an $85 million budget and a staff of 250. The Bulldogs won 13 national championships and 19 SEC titles during Evans’ tenure. Under Evans’ guidance, Georgia annually finished in the top 10 in the Learfield Director’s Cup and also amassed $65 million for the athletic department’s reserve fund, an increase of over $56 million in just a six-year period. Student-athletes achieved the highest-ever graduation success rate at Georgia in his final year as director of athletics. 

Prior to Maryland, Evans’ roles included managing partner at Evolution Sports Partners in New Jersey, vice president of fundraising at IMG College in Winston-Salem, N.C., and vice president of business development at the Markley Group in Boston. 

He earned a bachelor’s degree in finance in 1992 and a master’s degree of education in sports management in 1994, both from the University of Georgia, where he was also a four-year starter on the football team. 

Evans takes the helm as the Maryland Terrapins continue to mourn the recent loss of a student-athlete, which has prompted a university-issued external review. The review, which will look at all policies and protocols, could take up to 90 days. 

He will assume the position of Athletic Director on July 2. A press conference will take place tomorrow, June 26. Additional details will follow.

COLLEGE PARK, Md.— The University of Maryland announced today it has joined the Capital CoLAB (Collaborative of Leaders in Academia and Business) in an effort to help drive innovation and groundbreaking digital technology education in the region. Launched by the Greater Washington Partnership, the collaboration is a first-of-its-kind alliance of university and business leaders who have come together to take action to strengthen the capital region­, spanning Baltimore to Richmond, and position the region as a leading global hub for innovation. The initiative is a milestone in the capital region coming together, across sectors and geographic boundaries, to harness the region’s unique strengths and growth potential.

Connecting the District of Columbia, Maryland and Virginia’s leading higher education institutions and employers through multi-university and multi-business initiatives, the CoLAB will help realize the full potential of the capital region’s assets at unmatched scale and drive future economic growth, opportunity and prosperity. The Collaborative’s overall efforts will center on three broad areas: developing the talent and workforce the region needs now and in the future; developing cutting-edge technology capabilities to position the region for global leadership; and improving awareness of the super-region as a leading innovation hub.

“Working together, we can prepare a new generation of workers and business leaders, as well as the technology that will create new industries,” said University of Maryland President Wallace D. Loh. “The power of this initiative can be seen in our many successful partnerships."

Capital CoLAB will initially work on two major initiatives. The first will create unique regionwide credentials to increase the quantity and quality of digital technology talent emerging from local undergraduate programs. Developed jointly by businesses and universities, the credentials will be recognized by regional businesses as differentiators in hiring and deploying talent. The Business-Higher Education Forum is partnering with the Collaborative to develop student pathways to earn the credentials. The digital technology credentials are part of the Business Roundtable’s new Workforce Partnership Initiative (WPI)to tackle current and future skills development challenges and drive economic growth in seven regions, including the capital region, around the United States.

The second will showcase the region’s leadership in important digital technology innovations. The Tech Showcase will highlight the “best of” innovative research, technology application and thought-leadership. The event will reinforce the value of strong partnerships between academic institutions, industry and government and elevate the perception of the capital region as a producer of digital technology research and top talent.

“Today’s launch of the Capital CoLAB is a landmark moment, signaling the progress our region has made in breaking down barriers and coming together. Our region has enormous potential to become a leader in the global economy for years to come, but only if we work together to leverage our strengths across sectors and disciplines. The strength of this group of leading businesses and educational institutions is profound and demonstrates the uniqueness of the capital region,” said Jason Miller, Chief Executive Officer of the Greater Washington Partnership.

In addition to UMD, the Collaborative includes American University, Georgetown University, George Mason University, Howard University, Johns Hopkins University, University of Maryland, Baltimore County, University System of Maryland and University of Richmond, as well as Capital One, Exelon, EY, JPMorgan Chase & Co., Medimmune, MedStar Health, Monumental Sports & Entertainment, McKinsey & Company, Northrop Grumman Corporation and Under Armour.

The capital region has the third largest digital technology workforce in the United States. The region’s institutions contribute to one of the most robust and interconnected environments for innovation in the world.

 

About the Greater Washington Partnership

The Greater Washington Partnership is a first-of-its-kind civic alliance of CEOs in the region, drawing from the leading employers and entrepreneurs committed to making the capital region—from Baltimore to Richmond—one of the world’s best places to work, raise a family and build a business.

COLLEGE PARK, MD—The University of Maryland Center for Art and Knowledge at The Phillips Collection has awarded its 2018–19 Fellowship in Modern and Contemporary Art History to Dr. Ashley Lazevnick, a 2018 graduate of Princeton University. 

Headshot of Dr. Ashley LazevnickThe Phillips Collection and the University of Maryland host one postdoctoral fellowship during the academic year. This fellowship allows recipients to work with the Phillips’s exceptional collection of modern and contemporary art and the University of Maryland’s leadership programs in art historical scholarship, interdisciplinary experimentation, and virtual technologies. During the academic year, fellows teach at least one public lecture and participate in other programs and discussions with scholars, critics, museum staff, and students at the museum and university.

“Dr. Lazevnick's rigorous and interdisciplinary approach combining archival research and close visual analysis of American Modernism parallels with the passions of the Phillips and University of Maryland partnership,” said Dr. Klaus Ottmann, Deputy Director for Curatorial and Academic Affairs at the Phillips. “We are pleased to announce Dr. Ashley Lazevnick as our 2018-19 fellow.”

“We offer our congratulations to Dr. Ashley Lazevnick and look forward to supporting the development of her survey of American Precisionist art,” said Mary Ann Rankin, Senior Vice President and Provost at the University of Maryland. “Her work will continue to advance scholarship and innovation in the arts—the cornerstone of our partnership with The Phillips Collection.”

Ashley Lazevnick completed her doctorate's in American art at Princeton University in 2018. She holds an Master of Arts in the History of Art from Williams College and a Bachelor of Arts in Art History and English from Colgate University.

While at The Phillips Collection, Lazevnick will revise her dissertation into a book manuscript. Through an investigation of the term “precision” in art criticism, poetry, philosophy, and science in the early-20th century, her project reconsiders American Precisionist painting. A movement recognized today for meticulous paintings of skyscrapers and empty factories, Precisionism just as frequently included pictures of country barns, domestic interiors, and still lifes, in media as various as drawing, lithography, watercolor, pastel, and photography. 

More broadly, Lazevnick specializes in the visual and literary cultures of modernism, with particular focus on American art. Attentive to the interactions among different media, her research continually engages the nature of art writing, especially the use of non-normative genres (such as poetry) in reframing critical approaches to art. Her work has appeared in Word & Image as well as publications for the Warburg International Seminar, Florida State University, and the Ashmolean Museum. Future essays will appear in American Art and collected volumes on American Art for the Wallraf-Richartz-Museum and Merrell Publishing in London. Her research has been supported by fellowships with the Smithsonian American Art Museum, The Harry Ransom Center, the American Council of Learned Societies, the Terra Foundation, and the Metropolitan Museum of Art.
