Photonic chip is key to 'nurturing' quantum computers: A team from Bristol’s Quantum Engineering labs has shown how 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. A team has now shown how to protect qubits from errors using photons in a silicon chip.
