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 ...

An unprecedently large quantum simulator could shed light on how exotic, potentially useful quantum materials work and help us optimise them in the future. Quantum computers may eventually harness ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has ...

An analog-digital approach to quantum simulation could lay the foundations for the next generation of supercomputers to finally outpace their classical predecessors. Reading time 3 minutes Quantum ...

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 ...

Quantum simulation enables scientists to simulate and study complex systems that are challenging or even impossible using classical computers across various fields, including financial modelling, ...

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 ...
