On the correction of anomalous phase oscillation in entanglement witnesses using quantum neural networks
(IEEE, 20131001)Entanglement of a quantum system depends upon the relative phase in complicated ways, which no single measurement can reflect. Because of this, "entanglement witnesses'' (measures that estimate entanglement) are necessarily ... 
A quantum neural network computes its own relative phase
(IEEE, 20130417)Complete characterization of the state of a quantum system made up of subsystems requires determination of relative phase, because of interference effects between the subsystems. For a system of qubits used as a quantum ...
