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... Continue Reading
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...

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. Continue Reading
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. Continue Reading
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,... Continue Reading
JQI Graduate Student Receives DOE Fellowship

Elizabeth Bennewitz, a first-year physics graduate student at JQI and the Joint Center for Quantum Information and Computer Science (QuICS), has received a Department of Energy Computational Science Graduate Fellowship. Bennewitz is one of 33 recipients in 2022—the largest number of students this program has ever selected in a year. Continue Reading
Bilayer Graphene Inspires Two-Universe Cosmological Model

Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by astronomical measurements. Others linger on as mere possibilities or mathematical curiosities. In a new paper in Physical Review Research, JQI Fellow Victor  have explored the imaginative possibility that our reality is only one half of a pair of interacting worlds. Their mathematical model may provide a new perspective for looking at fundamental features of reality—including why our universe expands the way it does and how that relates... Continue Reading
