Much of modern electronic and computing technology is based on one idea: Add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in different ways […]
How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. “We should expect to see not only […]
Prof. Duanduan Wan and Prof. Meng Xiao at the School of Physics of Wuhan University recently published a study in the journal National Science Review. Their work provides a simple while intuitive example, demonstrating with […]
U.S. President Joe Biden signed the “Quantum Computing Cybersecurity Preparedness Act” yesterday, according to a memo from The White House. The bipartisan law encourages the federal government to adopt technology that is protected from decryption […]
Every Quanta article, video and podcast has its own backstory. By the time it arrives on your screen, our staff has nurtured it through weeks (and sometimes months) of careful work: research, reporting, writing, editing, […]
The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing […]
Executive Summary As 2022 came to an end and winter settled in, the French quantum community heated up. The ecosystem was busy across all the segments that make up this emerging industry — from government […]
Quantum 6, 884 (2022). https://doi.org/10.22331/q-2022-12-22-884 Quantum speed limits (QSLs) identify fundamental time scales of physical processes by providing lower bounds on the rate of change of a quantum state or the expectation value of an […]
Quantum 6, 883 (2022). https://doi.org/10.22331/q-2022-12-22-883 Equivalent approaches to determine eigenfrequencies of the Liouvillians of open quantum systems are discussed using the solution of the Heisenberg-Langevin equations and the corresponding equations for operator moments. A simple […]
A recent Nature publication continues to generate headlines over its findings that scientists from the California Institute of Technology developed a model of a traversable wormhole on the Google Sycamore quantum processing system. Click to […]
