Distilling entanglement from random cascades with partial “ Which Path ” ambiguity
We develop a framework to calculate the density matrix of a pair of photons emitted in a decay cascade with partial " which path " ambiguity. We describe an appropriate entanglement distillation scheme which works also for certain random cascades. The qualitative features of the distilled entanglement are presented in a two dimensional " phase diagram ". The theory is applied to the quantum tom...
متن کاملDistilling entanglement from cascades with partial “ Which Path ” ambiguity
We study cascades with partial which path ambiguity where entan-glement is distilled by spectral filtering. We develop a framework to calculate the amplitudes and phases of the density matrix. The results can be summarized in a two dimensional " phase diagram ". The theory is applied to the quantum tomography of the decay cascade of a biex-citon in a semiconductor quantum dot. The effect of inh...
متن کاملDistilling Entanglement from Fermions
Since Fermions are based on anti-commutation relations, their entanglement can not be studied in the usual way, such that the available theory has to be modified appropriately. Recent publications consider in particular the structure of separable and of maximally entangled states. In this talk we want to discuss local operations and entanglement distillation from bipartite, Fermionic systems. T...
متن کاملQuantum random number generator using photon-number path entanglement.
We report a quantum random number generator based on the photon-number-path entangled state that is prepared by means of two-photon quantum interference at a beam splitter. The randomness in our scheme is truly quantum mechanical in origin since it results from the projection measurement of the entangled two-photon state. The generated bit sequences satisfy the standard randomness test.
