But such measurements are notoriously challenging: the instruments used are themselves governed by quantum laws, and their interaction with particles can alter the very properties they are meant to ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

RIKEN scientists tap into AI to find a smarter method for fixing quantum errors, cutting resource demands for stable quantum machines. Theoretical physicists at RIKEN have made a key advance in ...

Quantum computers can perform complex computations thanks to their ability to represent an enormous number of different states at the same time in a so-called quantum superposition. Representing these ...
