Researchers Devise a Way to Protect Qubits from Errors Using Photons in a Silicon Chip

Quantum computers are gaining pace. They promise to provide exponentially more computing power for certain very tricky problems. They do this by exploiting the peculiar behaviour of quantum particles, such as photons of light. However, quantum states of particles are very fragile. The quantum bits, or qubits, that underpin quantum computing pick up errors very […]
