A sequence of classical laser pulses are injected into the chip and coupled into micro-resonators, generating special optical states called squeezed states.
These states consist of a quantum superposition of different numbers of photons, and exit the resonators into a set of bus waveguides.
The squeezed states then propagate into a network of phase shifters and beam splitters called an interferometer. This stage makes up the set of quantum gates.
Most of the information specified by the Strawberry Fields user is encoded via these gates. By setting voltages across electronic phase shifters, a gate sequence is loaded into the chip and applied to the squeezed states.
The entangled quantum state programmed by the user is then coupled back out of the chip for readout.
Most viable approach towards large scale quantum computers, leveraging mature silicon computing manufacturability and light's ability to carry information across networks.
Towards fault-tolerance via robust error-resistant physical qubits and flexibility in designing error-correcting codes.
Operates primarily at room temperature and easily integrates into existing telecommunication infrastructure, enabling a system that can be housed in a standard, compact server rack and installed in regular data centers.
