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

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 ...

Encryption—the process of sending a scrambled message that only the intended recipient’s device can decode—allows private and public sectors alike to safeguard information. Traditional encryption uses ...

Quantum mechanics remains a cornerstone of modern physics, providing a framework for understanding phenomena at the microscopic scale. At the heart of its formulation lies the concept of Hilbert ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

It has long been a mystery why pure math can reveal so much about the nature of the physical world. Antimatter was discovered in Paul Dirac’s equations before being detected in cosmic rays. Quarks ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

Albert Einstein famously said that quantum mechanics should allow two objects to affect each other’s behaviour instantly across vast distances, something he dubbed “spooky action at a distance” 1.

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.

A wild theory suggests that consciousness may explain quantum mechanics, by forcing the subatomic particles to choose one concrete outcome. When you purchase through links on our site, we may earn an ...
