The D-Wave computer operates as an adiabatic quantum computer, and consists of a superconducting 128-qubit chip in a cryogenics system within a 10 square meter room.
When they had rung in with correct meter readings after receiving estimated bills, EDF's automated system had charged all the additional units - if there were any - at its higher tariff rates following a general price rise.
Atop the 10-meter cubed space sits a motion capture system (made up of eight cameras) which locate objects in the FMA at rates of more than 200 frames per second.
