A Canadian company working with their US partners has made a quantum computing platform publicly available. Applicants can access 8, 12, and soon 24 qubit machines over the cloud. In the coming months, the company will release a blueprint for photonic quantum computing that is essentially a primer on how to scale to millions of qubits in a fault-tolerant manner. They use continuous variable quantum computing which relies on “squeezed states” consisting of superpositions of multiple photons. Squeezed states take advantage of Heisenberg’s uncertainty principle reducing the uncertainty in the measurements of a given variable while increasing the uncertainty in the measurement of another variable the researchers can ignore…read more.
