Quantum longitude - keeping track of qubits in the quantum sea

Quantum computing depends exquisitely on the parts of a quantum system remaining coherent long enough---even in the face of environmental noise---for the computation to be performed. A proposed scheme should be helpful in sustaining coherence by carefully making mid-calculation corrections.

Researchers make first all-optical nanowire switch

Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.
