Quantum annealers are devices that physically implement a quantum system called the 'Ising model' to solve combinatorial optimization problems. However, the coefficients of the Ising model often ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

Ising machines can solve certain combinatorial optimization problems, but their efficiency could be improved with multi-spin flips. ... (which is an energy function of the Ising model).

The Ising model was first developed 100 years ago to describe magnetic phase transitions. Atoms in a solid can have one of two spin states (up or down) and interact with their neighbours. This ...

More recently, researchers at Canadian company D-Wave and elsewhere have looked to devices known as adiabatic quantum computers. These exploit the phenomenon of quantum tunnelling to place a set of ...

The Ising model provides a rich framework for thinking about the interactions between components of a system in terms of energy. It is a very basic idea, but a powerful one.
