Graphs May Prove Key in Search for Holy Grail of Quantum Error Correction

In February 2019, JQI Fellow Alicia Kollár, who is also an assistant professor of physics at UMD, bumped into Adrian Chapman, then a postdoctoral fellow at the University of Sydney, at a quantum information conference. Although the two came from very different scientific backgrounds, they quickly discovered that their research had a surprising commonality. They both shared an interest in graph theory, a field of math that deals with points and the connections between them. Their ensuing collaboration resulted in a new tool that aids in the search for new quantum error correction schemes—including the Holy Grail of self-correcting quantum error correction. They published their findings recently in the journal Physical Review X Quantum.

Nobel Prize Highlights One of Quantum’s Signature Quirks

The 2022 Nobel Prize in physics has been awarded to three physicists for their experiments with entangled photons—particles of light with intrinsically entwined quantum fates. The prize will be split equally between Alain Aspect, John Clauser and Anton Zeilinger.

Maryland Quantum-Thermodynamics Hub Founded with $2M Grant

The University of Maryland is hosting a new $2 million project aimed at making the state of Maryland a central hub for research in the emerging field of quantum thermodynamics, which studies the rules that govern how energy flows in quantum systems. The Maryland Quantum-Thermodynamics Hub, supported by a grant from the Templeton Foundation, will bring together researchers from several universities to galvanize a field that is central to understanding our universe and to developing robust quantum technologies.

Quantum Gases Keep Their Cool, Prompting New Mysteries

Quantum physics is a notorious rule-breaker. For example, it makes the classical laws of thermodynamics, which describe how heat and energy move around, look more like guidelines than ironclad natural laws. In some experiments, a quantum object can keep its cool despite sitting next to something hot that is steadily releasing energy. A new experiment led by David Weld, an associate professor of physics at the University of California, Santa Barbra (UCSB), in collaboration with JQI Fellow Victor Galitski, shows that several interacting quantum particles can also keep their cool—at least for a time. In a paper published in Nature Physics on tk, Galitski, who is also a Chesapeake Chair Professor of Theoretical Physics in the Department of Physics at UMD, and the researchers at UCSB describe the experiment, which is the first to explore this behavior, called dynamical localization, with interactions included.

Recent Physics Grad Sees Many Roads Ahead

As Jeffrey Wack walked across the graduation stage in May 2022, he carried with him a lot of uncertainty about where to go next. His trepidation came from his voracious curiosity for a broad range of things, primarily within physics and math—the subjects of his two degrees—but also from his interests in teaching, outreach and music. The prospect of having to pick just one path forward felt confining to Wack. But that same curiosity served him extremely well during his time at the University of Maryland, and it left him with many opportunities for next steps.Wack collected an impressive resume at UMD. He taught an introductory course on nuclear physics and reactor operations, studied physics in Florence, participated in an optomechanics research project that resulted in a publication, made significant contributions to experimental research with coplanar waveguides, and co-taught a self-designed course on music theory and math. Since graduating, he began working as a fellow at the Museum of Math in New York City, sampling the working world while contemplating graduate school.

Diving into UMD’s Quantum Community

The University of Maryland has a flourishing physics program that offers ambitious students opportunities to engage in basic research and learn how quantum physics is being harnessed in cutting-edge quantum technologies. Last year, as a freshman physics major at UMD, LeSchack wasted no time before connecting with faculty, embracing the resources offered by the university and even creating new opportunities for herself and her fellow undergrads in the form of a quantum club.

Quantum-Safe Algorithms Face Off in NIST’s Cryptography Showdown

While browsing the web, you might not realize that the security of your online transactions is guaranteed by a hard-to-crack math problem called factoring. But this security could evaporate in an instant—if a big enough quantum computer is built. Computers that store information in quantum hardware—like individual ions, atoms or photons—would make quick work of the factoring problem and threaten the safety of current protocols. To thwart the threat posed by possible quantum computers, the National Institute of Standards and Technology (NIST) has been running a kind of competition.

JQI Alum Receives International Early-Career Award

Pablo Solano, a former graduate student at JQI and current assistant professor at the University of Concepción in Chile, has been named a Canadian Institute for Advanced Research (CIFAR) Azrieli Global Scholar. Solano is one of 18 researchers selected this year from more than 200 applicants to receive support from the program.

Quantum Computers Are Starting to Simulate the World of Subatomic Particles

There is a heated race to make quantum computers deliver practical results. But this race isn't just about making better technology—usually defined in terms of having fewer errors and more qubits, which are the basic building blocks that store quantum information. At least for now, the quantum computing race requires grappling with the complex realities of both quantum technologies and difficult problems. To develop quantum computing applications, researchers need to understand a particular quantum technology and a particular challenging problem and then adapt the strengths of the technology to address the intricacies of the problem. Theoretical nuclear physicist Zohreh Davoudi, an assistant professor of physics at the University of Maryland (UMD) and a member of the Maryland Center for Fundamental Physics, has been working with multiple colleagues at UMD to ensure that the problems that she cares about are among those benefiting from early advances in quantum computing. Davoudi and JQI Fellow Norbert Linke are collaborating to push the frontier of both the theories and technologies of quantum simulation through research that uses current quantum computers. Their research is intended to illuminate a path toward simulations that can cut through the current blockade of fiendishly complex calculations and deliver new theoretical predictions. The team’s current efforts might help nuclear physicists, including Davoudi, to take advantage of the early benefits of quantum computing instead of needing to rush to catch up when quantum computers hit their stride.In a new paper in PRX Quantum, Davoudi, Linke and their colleagues have combined theory and experiment to push the boundaries of quantum simulations—testing the limits of both the ion-based quantum computer in Linke’s lab and proposals for simulating quantum fields.
