Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has ...

What happens if you embed an ultrafast quantum computer inside a diamond (you know, aside from qualifying for sale in one of Tiffany’s catalogues and inviting “forever” computing quips)? Answer: You ...

About 50 Google physicists are making history inside a mundane white building in Goleta, next door to a used furniture warehouse and a small local brewery. They say they built a new kind of computer ...

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems.

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

Large quantum computers may be able to solve problems impossible for even the best traditional supercomputers – but in order to do so, some of them might need far more energy than those supercomputers ...
