A photon enters an extraordinarily intense laser field. When it exits, its polarization has rotated, as though empty space ...

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 ...

The development of quantum simulation is expected to provide unique capabilities for exploring the complex emergent phenomena and dynamics governed by the fundamental strong and electroweak ...

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

While quantum computers continue to slowly grind towards usefulness, some are pursuing a different approach—analog quantum simulation. This path doesn’t offer complete control of single bits of ...

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 ...

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 ...

Illustration of a quantum simulator with atoms trapped into a square lattice with lasers. The small spheres at the corners are atoms in their lowest energy state. The ones inside a blue sphere are ...
