Quantum computing’s edge looked closer after a hard physics problem seemed beyond classical machines. But a new result shows ...

Using a conventional computer and cutting-edge mathematical tools and code, physicists at the Center for Computational ...

Researchers have successfully used a quantum algorithm to solve a complex century-old mathematical problem long considered impossible for even the most powerful conventional supercomputers. The ...

For years, the world has been told that quantum computers would soon leave classical computers behind. The phrase “quantum supremacy” became a technological slogan— the belief that ordinary computers ...

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 ...

For the past six years, Los Alamos National Laboratory has led the world in trying to understand one of the most frustrating barriers that faces variational quantum computing: the barren plateau.

Quantum technologies promise powerful new kinds of computers, giving scientists new tools to mimic and explore nature at its ...

The standard assumption is that Q-Day, when a cryptographically relevant quantum computer will be able to break today's encryption, is still several years away. However, this misses the point.
