Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle properties like charge and spin. For decades, […]
Scientists have created a Bose-Einstein condensate out of excitons — quasiparticles that combine electrons and positively charged ‘holes’ — in a semiconductor. Quasiparticle Bose-Einstein condensates have for six decades been something of a holy grail […]
Extreme miniaturization of infrared (IR) detectors is critical for their integration into next-generation consumer electronics, wearables and ultra-small satellites. Thus far, however, IR detectors have relied on bulky (and expensive) materials and technologies. A team […]
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. […]
Wordle has fast become a modern classic played by millions. As a puzzle enthusiast, I feel as thrilled by it as an astronomer seeing a visible supernova. Only twice before have I felt and seen […]
My name is Anders Liman. I’m a graduate student studying Tech Ethics and Science Policy at Duke University. I also hold a master’s in Computer Science from North Carolina State University. This summer, as part […]
Quantum computers, which can perform calculations much faster than traditional computers, have a big problem: They are prone to data storage and processing errors caused by disturbances from the environment like vibrations and radiation from […]
Quantum 6, 847 (2022). https://doi.org/10.22331/q-2022-10-25-847 Tracing out the environmental degrees of freedom is a necessary procedure when simulating open quantum systems. While being an essential step in deriving a tractable master equation it represents a […]
Insider Brief Sandia National Laboratories envisions quantum inertial sensors as revolutionary, onboard navigational aids. The researchers will need to reengineer the sensor into a compact, rugged device so that the technology could safely guide vehicles […]
Quantum 6, 846 (2022). https://doi.org/10.22331/q-2022-10-25-846 Stabilizer states and graph states find application in quantum error correction, measurement-based quantum computation and various other concepts in quantum information theory. In this work, we study party-local Clifford (PLC) […]
