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

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

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

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

Imagine the tap of a card that bought you a cup of coffee this morning also let a hacker halfway across the world access your bank account and buy themselves whatever they liked. Now imagine it wasn’t ...

Abstract Catalysis refers to the possibility of enabling otherwise inaccessible quantum state transitions by supplying an auxiliary system, provided ...

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 a platform ...

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 ...
