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 ...

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.

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 ...

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

The 2026 Turing Award celebrates quantum cryptography's inventor and pioneers. Learn how their physics-based security model defends global data against next-generation quantum computers.

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.

John von Neumann came about as close as humanly possible to embodying the Platonic ideal of a genius. Conversant in ancient Greek by age 6, the Hungarian made significant mathematical advances in his ...
