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.
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 a ...
Four RIKEN researchers have used two small quantum computers to simulate quantum information scrambling, an important quantum-information process. This achievement illustrates a potential application ...
One of the most promising uses for quantum computers is to simulate proteins that could help us discover new drugs, but these devices are currently too error-prone for the task. However, two quantum ...

You’re living in a simulation and wouldn’t even know
What if your reality was nothing more than a complex computer simulation? And if you were just a program on someone else’s hard drive, how would you know? Who would be controlling your every move?
