Building a working quantum internet would require overcoming a host of technical challenges, but researchers who have built ...

In the 1980s, John Clarke, Michel Devoret and John Martinis demonstrated quantum effects in an electric circuit, an advance that underlies today’s quantum computers.

Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called ...
