Physicists have built a new type of digital-analogue quantum simulator in Google’s laboratory, which can be used to study physical processes with unprecedented precision and flexibility. Two ...

Faithful simulations of the world are impossible to create using ordinary computers. Simulating physical reality is, however, the original, express purpose of quantum computers. In 1981, long before ...

This image depicts the ultracold atomic quantum simulator. The red and blue balls represent the fermionic atoms with up and down spins, respectively, arranged in a staggered pattern in 3D space, ...

In a study published in Nature, a research team has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM).

Researchers have invented a new method by which classical computers can measure the error rates of quantum machines without having to fully simulate them. Quantum ...
