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

JQI Grad Student Wins UMD Three-Minute Thesis Competition

JQI graduate student Jacob Bringewatt is one of four post-candidacy student winners in the campus-wide portion of the UMD Three-Minute Thesis (3MT) competition. Each of these four winners received $1000. Each will be further evaluated by the UMD Graduate School, and one will be selected to represent the university in an international 3MT competition. In these events, the competitors must distill the research project that they are dedicating years of their life to into a three-minute presentation that is accessible to someone unfamiliar with the topic.

JQI Fellow Kollár Bridges Abstract Math and Realities of the Lab

The research of JQI Fellow Alicia Kollár, who is also a Chesapeake Assistant Professor of Physics at the University of Maryland, embodies the give and take between physics and mathematics. In her lab, she brings abstract theories to life and in turn collaborates on new theorems. She has forged a research program of manipulating light on a chip, coaxing the light into behaving as though it lives on the surface of a sphere, or a mathematical abstraction known as a hyperbolic surface. She also collaborates with mathematicians, furthering both the understanding of what these chips can do and their underlying... Continue Reading

Growing into a Physicist at UMD

JQI graduate student Michael Winer has had a relationship with physics—and physics at the University of Maryland in particular—since he was a kid. He first came to UMD as a high school student pursuing his competitive spirit when physics was a fun challenge. Then over time, physics became something more nuanced for him. Now, he has returned to UMD to pursue physics as a career and is also helping introduce the joys of physics to a new generation of bright young minds. Continue Reading

New Perspective Blends Quantum and Classical to Understand Quantum Rates of Change

There is nothing permanent except change. This is perhaps never truer than in the fickle and fluctuating world of quantum mechanics. The quantum world is in constant flux. The properties of quantum particles flit between discrete, quantized states without any possibility of ever being found in an intermediate state. How quantum states change defies normal intuition and remains the topic of active debate—for both scientists and philosophers. The rules governing things like billiards balls and the temperature of a gas look very different from the quantum rules governing things like electron collisions and the energy absorbed or released by a...

Nicole Yunger Halpern Ponders Quantum Mechanics, Thermodynamics, and Everything Else

There is a well-known saying, of disputed origin, that dissuades students and even working physicists from thinking too deeply about the meaning behind quantum physics. “Shut up and calculate,” it goes. Nicole Yunger Halpern, an affiliate of JQI and the newest Fellow of the Joint Center for Quantum Information and Computer Science (QuICS), was never one to abide by this mantra. Instead, Yunger Halpern, who is also a physicist at the National Institute of Standards and Technology, brings a vast intellectual curiosity to physics, from tackling abstract theory to collaborating with experimentalists, all the while drawing distinct connections between diverse...
