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

Nation-states and malicious actors are collecting encrypted data so they can read it with future quantum computers. These ...

Cryptography pioneers Charles Bennett (left) and Gilles Brassard introduced the BB84 protocol the uses the principles of ...

Quantum gravity strives to reconcile the seemingly disparate realms of general relativity and quantum mechanics. Central to this endeavour is the realisation that classical concepts of spacetime may ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but it turns out light also follows the fundamental phenomenon.

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

Physicists at the University of the Witwatersrand in Johannesburg have identified a hidden geometric structure reaching 48 ...

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 ...
