A quantum web page

In quantum teleportation, an unknown quantum state is transmitted from one party to another using only local operations and classical communication, at the cost of shared entanglement. Is possible similarly, using an N party entangled state, to have the state retrievable by any of the N − 1 possible receivers? If the receivers cooperate, and share a suitable state, this can be done reliably. Th...

Quantum Information and the Problem of Time

Abstract. In many cases tensor universality implies that multi-partite quantumstate processing is determined by what happens in totally disentangled cases. In independent systems relative time direction for the parts is arbitrary. This hints that time may be linked to entanglement and measurements and that there may be a measurement-only version of quantum mechanics. One-way quantum computation...

A model and a technique developed by Wing and Kristofferson (1973) decomposes variance of timing into that putatively due to a central timekeeper (a clock) and that due to implementation of movement through the motor system. A patient with unilateral cerebellar damage, when attempting to tap out a regular series of intervals, showed a large increase in timing variability for the left hand convi...
