holy_calamity writes: The first quantum computer chips have been made by two US groups, New Scientist reports. Both NIST and Yale demonstrated chips where information was transferred between two superconducting qubits using a 'quantum bus'. The bus is made from a cavity that traps a single microwave photon as a standing wave — the NIST group also managed to use the bus to store data from one qubit for a short time.
