Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.

A new study explores how EOS transmits ultrashort laser pulses through crystals that change in response to an applied electric field. This technique allows researchers to accurately capture the shape ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

In the 100th-anniversary year of quantum mechanics, which describes the universe at its smallest, most fundamental scales, the 2025 Nobel Prize in Physics has gone to three pioneers in bringing its ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...
