Yale scientists make 2 giant steps in advancement of quantum computing

arried directly to the target qubit. A novel feature of this experiment is that the photon used is only virtual, said Majer and Chow, winking into existence for only the briefest instant before disappearing.

To allow the crucial communication between the many elements of a conventional computer, engineers wire them all together to form a data bus, which is a key element of any computing scheme. Together the new Yale research constitutes the first demonstration of a quantum bus for a solid-state electronic system. This approach can in principle be extended to multiple qubits, and to connecting the parts of a future, more complex quantum computer.

However, Schoelkopf likened the current stage of development of quantum computing to conventional computing in the 1950s, when individual transistors were first being built. Standard computer microprocessors are now made up of a billion transistors, but first it took decades for physicists and engineers to develop integrated circuits with transistors that could be mass produced.
