The papers were peer reviewed.Quantum communications, measurement and computing embodies the fledgling science of quantum information. It applies quantum physics to tackle the challenges of next generation information processing. The conference was the seventh in the series. These proceedings describe papers presented at the meeting and represent the forefront of current research. Topics include: quantum communication, measurement, quantum computation, entanglement, quantum cryptography, sources of quantum states, time, as well as dissipation and decoherence.Frequency (Hz) Time (sec) A schematic of the test setup for measurement of the photon number statistics is shown in Fig 1(b). Signal light is incident to the InGaAs PIN photodiode in the cryostat through a single mode fiber with a focuser. ...
