Weak Measurements with Entangled Probes
arXiv:0802.2042 · doi:10.1103/PhysRevA.77.062105
Abstract
Encoding the imaginary part of a weak value onto an initially entangled probe can modify its entanglement content - provided the probe observable can distinguish between states of different entropies. Apart from fundamental interest, this result illustrates the utility of the imaginary weak value as a calculational tool in certain entanglement concentration protocols.
