UMD to host 200 scientists for quantum error correction conference

Nearly 200 researchers from around the world will descend on the University of Maryland campus next week for the 4th International Conference on Quantum Error Correction (QEC17), the world’s premier scientific meeting focused on protecting quantum computers from their hostile surroundings.

This year’s conference, which will be held Sept. 11–15, is organized by researchers from the Joint Center for Quantum Information and Computer Science (QuICS) and Georgia Tech.

Long-range interactions leave a quantum reminder

Given enough time, a forgotten cup of coffee will lose its appeal and cool to room temperature. One way of telling this tepid tale involves a stupendous number of coffee molecules colliding like billiard balls with themselves and colder molecules in the air above. Those constant collisions siphon energy away from the coffee, bit by bit, in a process that ...

Long live MATHUSLA

More than 300 feet underground, looping underneath both France and Switzerland on the outskirts of Geneva, a 16-mile-long ring called the Large Hadron Collider (LHC) smashes protons together at nearly the speed of light. Sifting through the wreckage, scientists have made some profound discoveries about the fundamental nature of our universe.

But what if all that chaos underground is shrouding subtle hints of new physics? David Curtin, a postdoctoral researcher at the Maryland Center for Fundamental Physics here at UMD, has an idea for a detector that could be built at the surface—far away from the noise and shrapnel of the main LHC experiments. The project, which he and his collaborators call MATHUSLA, may resolve some of the mysteries that are lingering behind our best theories.

Atomic cousins team up in early quantum networking node

Large-scale quantum computers, which are an active pursuit of many university labs and tech giants, remain years away. But that hasn’t stopped some scientists from thinking ahead, to a time when quantum computers might be linked together in a network or a single quantum computer might be split up across many interconnected nodes.

A group of physicists at the University ...

Labs IRL: Boxing up atomic ions

What makes a university physics lab tick? Sean Kelley grabs a mic and heads to a lab that's trying to build an early quantum computer out of atomic ions. Marko Cetina and Kai Hudek, two research scientsts at the University of Maryland who run the lab, explain what it takes to keep things from burning down and muse about the future of quantum computers.

This is the first installment of Labs in Real Life—Labs IRL, for short—a recurring segment on Relatively Certain that will explore what it's actually like to work in a university lab. (The work in this lab is supported by the Intelligence Advanced Research Projects Activity (IARPA) LogiQ Program through the U.S. Army Research Office.)

This episode of Relatively Certain was produced by Sean Kelley, Emily Edwards and Chris Cesare. It features music by Dave Depper, dustmotes and Podington Bear. Relatively Certain is a production of the Joint Quantum Institute, a research partnership between the University of Maryland and the National Institute of Standards and Technology, and you can find it on iTunes, Google Play or Soundcloud.

JQI student awarded NSF Graduate Research Fellowship

In Spring 2017, Jonathan Francisco San Miguel was awarded a National Science Foundation (NSF) Graduate Research Fellowship. This prestigious NSF fellowship recognizes outstanding students in science, technology, engineering and mathematics fields. Since 2014, he has been working on superconducting qubits in JQI Fellow Vladimir Manucharyan's condensed matter physics laboratory.

San Miguel's interest in physics started before coming to college. Later at ...

Tiny magnetic tremors unlock exotic superconductivity

Deep within solids, individual electrons zip around on a nanoscale highway paved with atoms. For the most part, these electrons avoid one another, kept in separate lanes by their mutual repulsion. But vibrations in the atomic road can blur their lanes and sometimes allow the tiny particles to pair up. The result is smooth and lossless travel, and it’s one ...

Quantum Thermometer or Optical Refrigerator?

From NIST News

In an arranged marriage of optics and mechanics, JQI-NIST physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest principles of quantum physics, these optomechanical systems can act as inherently accurate thermometers, or conversely, as a type ...

Neural networks take on quantum entanglement

Machine learning, the field that’s driving a revolution in artificial intelligence, has cemented its role in modern technology. Its tools and techniques have led to rapid improvements in everything from self-driving cars and speech recognition to the digital mastery of an ancient board game.

Now, physicists are beginning to use machine learning tools to tackle a different kind of problem, ...

The limits of computation

Modern computers, which dwarf their forebears in speed and efficiency, still can't conquer some of the hardest computational problems. Making them even faster probably won't change that.

Computer scientists working in the field of computational complexity theory explore the ultimate limits of computers, cataloguing and classifying a universe of computational problems. For decades, they’ve been stuck on a particular nagging question, which boils down to this: What’s the relationship between solving a problem and checking your work?

Chris Cesare teams up with Emily Edwards and QuICS postdoctoral researcher Bill Fefferman to explain what this question entails and how researchers are tackling it with tools from physics.

This episode of Relatively Certain was produced and edited by Chris Cesare, with contributions from Emily Edwards, Sean Kelley and Kate Delossantos. It features music by Dave Depper, Podington Bear, Kevin MacLeod and Little Glass Men. Relatively Certain is a production of the Joint Quantum Institute, a research partnership between the University of Maryland and the National Institute of Standards and Technology, and you can find it on iTunes, Google Play or Soundcloud.
