Quantum Simulation Stars Light in the Role of Sound

Inside a material, such as an insulator, semiconductor or superconductor, a complex drama unfolds that determines the physical properties. Physicists work to observe these scenes and recreate the script that the actors—electrons, atoms and other particles—play out. It is no surprise that electrons are most frequently the stars in the stories behind electrical properties. But there is an important supporting actor that usually doesn’t get a fair share of the limelight. This underrecognized actor in the electronic theater is sound, or more specifically the quantum mechanical excitations that carry sound and heat. Scientists treat these quantized vibrations as quantum mechanical particles...免费vmess节点

Diamonds Shine a Light on Hidden Currents in Graphene

It sounds like pure sorcery: using diamonds to observe invisible power swirling and flowing through carefully crafted channels. But these diamonds are a reality. JQI Fellow Ronald Walsworth and Quantum Technology Center (QTC) Postdoctoral Associate Mark Ku, along with colleagues from several other institutions, including Professor Amir Yacoby and Postdoctoral Fellow Tony Zhou at Harvard, have developed a way to use diamonds to see the elusive details of electrical currents. The new technique gives researchers a map of the intricate movement of electricity in the microscopic world. The team demonstrated the potential of the technique by revealing the unusual electrical... Continue Reading

New Quantum Information Speed Limits Depend on the Task at Hand
Faster algorithms and tighter theoretical limits narrow the gap between the possible and the doable.

Unlike speed limits on the highway, most speed limits in physics cannot be disobeyed. For example, no matter how little you care about getting a ticket, you can never go faster than the speed of light. Similarly stringent limits exist for information, too. The speed of light is still the ultimate speed limit, but depending on how information is stored and transmitted, there can be slower limits in practice.The story gets particularly subtle when the information is quantum. Quantum information is represented by qubits (the quantum version of ordinary bits), which can be stored in photons, atoms or any number of... Continue Reading

JQI Quantum Computing Results Selected as “Top Pick” by IEEE Micro

Research by a team that includes JQI Fellow Norbert Linke, UMD physics graduate student Nhung Hong Nguyen, and visiting graduate student Cinthia Huerta Alderete has been selected as one of the 2019 Top Picks in Computer Architecture by IEEE Micro. The work, which compared different kinds of quantum computers, was a collaboration with scientists from Princeton and IBM. IEEE Micro evaluates submissions to all computer architecture conferences that take place throughout the year and selects 12 as Top Picks for their novelty and potential for long-term impact. They invite Top Pick authors to prepare an article for the year’s special issue,... Continue Reading

JQI Fellow Vladimir Manucharyan has received a 2019 Google Faculty Research Award. It is the second consecutive year that Manucharyan, who is also an Associate Professor of Physics at UMD, has earned the honor. This year’s award will continue to support research by Manucharyan and his team into quantum computing hardware based on superconducting circuits. They are pursuing the development of special quantum bits—called fluxonium qubits—for use in a new generation of computers. Continue Reading

Quantum Gases Won’t Take the Heat

The quantum world blatantly defies intuitions that we’ve developed while living among relatively large things, like cars, pennies and dust motes. The quantum behavior of dynamical localization bucks the assumption that a cold object will always steal heat from a warmer object. Until now, dynamical localization has only been observed for single quantum objects, which has prevented it from contributing to attempts to pin down where the changeover occurs. JQI researchers and colleagues have investigated mathematical models to see if dynamical localization can still arise when many quantum particles interact. To reveal the physics, they had to craft models to account...免费vmess
