A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is.

Quantum catalysts are specialized resources that enable quantum state transformations previously thought impossible, holding ...

Two scientists just won computing's Nobel Prize for an idea from 1984: use quantum mechanics to make eavesdropping physically ...

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

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

An American physicist and Canadian computer scientist received the A.M. Turing Award on Wednesday for their groundbreaking work on quantum key cryptography.

Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.

Photo of the experimental setup to couple MWs to N- 𝑉⁢s using grape dimers. A stripped optical fiber with N- 𝑉 spins, cantilevered from a rod, lies between two grapes. The grapes were positioned on ...

Do games have anything deeper to say about physics, or vice versa? Maybe. Most surprisingly, the connection might arise at the most fundamental level of all: quantum physics. —Chiu Fan Lee and Neil F.
