When a negatively charged electron and a positively charged hole in a pair remain bound together following excitation by light, they produce states known as excitons. These states can influence the optical properties of materials, […]

There are different ideas about how quantum computers could be built. But they all have one thing in common: you use a quantum physical system—for example, individual atoms—and change their state by exposing them to […]
True to form, a “strange metal” quantum material proved strangely quiet in recent quantum noise experiments at Rice University. Published this week in Science, the measurements of quantum charge fluctuations known as “shot noise” provide […]
In recent years, physicists have been trying to better understand how quantum information spreads in systems of interacting particles—a phenomenon often referred to as “scrambling.” Scrambling in closed systems, physical systems that can only exchange […]
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another step […]
Writing in PRX Quantum, Nathan Goldman and Lucila Peralta Gavensky (Science Faculty, ULB) and their colleagues introduce a general framework for modifying and controlling the nature of nonlinearities in a broad class of physical systems, […]
Zero-knowledge proof (ZKP) is a cryptographic tool that allows for the verification of validity between mutually untrusted parties without disclosing additional information. Non-interactive zero-knowledge proof (NIZKP) is a variant of ZKP with the feature of […]
Processing quantum information relies on interacting qubits—the basic building blocks of quantum information—to perform computational tasks. Scientists are searching for the optimal qubit platform that can perform operations more efficiently, accurately and as fast as […]
As demand rises for increased data storage and faster-performing computers, researchers are creating a new generation of materials to meet consumers’ expectations. Click to rate this post! [Total: 0 Average: 0]You have already voted for […]
Quantum advantage is the milestone the field of quantum computing is fervently working toward, where a quantum computer can solve problems that are beyond the reach of the most powerful non-quantum, or classical, computers. Click […]
