Ancient Namibian stone could hold key to future quantum computers

A special form of light made using an ancient Namibian gemstone could be the key to new light-based quantum computers, which could solve long-held scientific mysteries, according to new research led by the University of St ...

Unusual quantum state of matter observed for the first time

It's not every day that someone comes across a new state of matter in quantum physics, the scientific field devoted to describing the behavior of atomic and subatomic particles in order to elucidate their properties.

Quantum physics offers new way to factor numbers

(Phys.org)—Any number can, in theory, be written as the product of prime numbers. For small numbers, this is easy (for example, the prime factors of 12 are 2, 2, and 3), but for large numbers, prime factorization becomes ...

Quantum simulation more stable than expected

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers. These problems are otherwise challenging for conventional computers. This brings such digital quantum simulation ...

AlphaZero learns to rule the quantum world

The chess world was amazed when the computer algorithm AlphaZero learned, after just four hours on its own, to beat the best chess programs built on human expertise. Now a research group at Aarhus University in Denmark has ...

A quantum leap in particle simulation

A group of scientists at the Department of Energy's Fermilab has figured out how to use quantum computing to simulate the fundamental interactions that hold together our universe.
