The rapidly-improving speed and versatility of digital computers has mostly driven analogue computers out of use in modern systems, as has the relative difficulty of programming an analogue computer.

Scientists have developed a new computer model that simulates how moon dust behaves in lunar gravity. They hope it will help future robotic moon explorers to do their job more safely. When you ...

Subatomic particles such as quarks can pair up when linked by ‘strings’ of force fields — and release energy when the strings are pulled to the point of breaking. Two teams of physicists have now used ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the ...

The notion that we live as characters in someone else’s video game is irresistible to many, even outside of science fiction bookshelves. Googling the term “simulation hypothesis” returns numerous ...

The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing ...

A quantum computer has been used to simulate a holographic wormhole for the first time. In this case, the word “holographic” indicates a way to simplify physics problems involving both quantum ...
