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 very ...

In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for ...
In a new study published in Physical Review Letters, scientists explore how small water jets can create stable periodic oscillations on a solid disk, uncovering a connection between these movements and the waves they generate ...
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional ...
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 ...
Proteins, the workhorses of biology, are encoded by DNA sequences and are responsible for vital functions within cells. Since the first experimental measurement of a protein structure was made by John Kendrew in the 1950s, ...

A little like humans, the nuclei of atoms tend to shrink as they lose weight. But atomic nuclei are complex quantum systems formed from neutrons and protons that are themselves composite particles made of quarks. As such, ...

Black holes are regions in space where the gravitational pull is so strong that nothing can escape them, not even light. These fascinating regions have been the focus of countless studies, yet some of the physics underlying ...
A new study using data from the CALorimetric Electron Telescope (CALET) instrument on the International Space Station has found evidence for nearby, young sources of cosmic ray electrons, contributing to a greater understanding ...
