EVER since the 1980s, researchers have been working on the development of a quantum computer that would be exponentially more powerful than any of the digital computers that exist today. And now ...

A high-performance silicon-based quantum processor has been developed in which the spins of nine phosphorus nuclei — divided into two groups, or registers — and two shared electrons act as quantum ...

The gap between conventional and quantum computers is closing when it comes to simulating scrambling of quantum information Figure 1: A close-up of the trapped-ion ...

Quantum computers are based on the principles of quantum mechanics. Compared with classical bits, qubits can be at the superposition between zero and one, so a quantum computer composed of qubits can ...
