Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator -- a specific ...

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 ...
