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 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.

On a warm afternoon last fall, Steven Caron, a technical artist at the video-game company Quixel, stood at the edge of a redwood grove in the Oakland Hills. “Cross your eyes, kind of blur your eyes, ...

A research team at the Jülich Supercomputing Center, together with experts from NVIDIA, has set a new record in quantum simulation: for the first time, a universal quantum computer with 50 qubits has ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift — all within millionths of ...

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 ...
