One advantage of systems that use atoms or ions is that we can move them around. This allows us to entangle any qubit with ...

Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum computing forward. But there's still much work to be done before they can be ...

Interference helps keep quantum bits (qubits) stable by reducing outside disruptions. It speeds up calculations by letting quantum computers explore many answers at once. Interference makes fixing ...

Quantum computers hold the potential to revolutionize the possibilities for solving difficult computational problems that would take classical computers many years to resolve. But for those computers ...
