qubits:Two Giant Steps In Advancement Of Quantum Computing Achieved

ScienceDaily: Two Giant Steps In Advancement Of Quantum Computing Achieved
"Science Daily — Two major steps toward putting quantum computers into real practice -- sending a photon signal on demand from a qubit onto wires and transmitting the signal to a second, distant qubit -- have been brought about by a team of scientists at Yale."
Qubits, the building blocks of a future quantum computer, become useful when quantum communication between them can be established. In our experiment, this job is done by photons in a cavity on a microchip. This way, quantum information is successfully shuttled back and forth between two superconducting qubits.
