Multi-purpose silicon chip created for quantum information processing

The Bristol team has been using silicon photonic chips as a way to try to build quantum computing components on a large scale and today’s result, published in the journal Nature Photonics, demonstrates it is possible to fully control two qubits of information within a single integrated chip. This means any task that can be achieved with two qubits, can be programmed and realised with the device.
