Lots of bits
Approximately 100 billion optical components would be required to make a practical, fault tolerant, quantum computer that uses light to process information. This is the conclusion of a recent publication which calculated that the number of components for a photon-based computer would be five orders of magnitude larger than for a matter-based processor.
