Entanglement purification of unknown quantum states
A concern has been expressed that “the Jaynes principle can produce fake entanglement” [R. Horodecki et al., Phys. Rev. A 59, 1799 (1999)]. In this paper we discuss the general problem of distilling maximally entangled states from N copies of a bipartite quantum system about which only partial information is known, for instance in the form of a given expectation value. We point out that there i...
متن کاملEntanglement conditions for multi-mode states
Zong-Guo Li, Shao-Ming Fei, Zhi-Xi Wang and Ke Wu 1 Department of Mathematics, Capital Normal University, Beijing 100037, China 2 Max Planck Institute for Mathematics in the Sciences, D-04103 Leipzig, Germany Abstract We provide a class of inequalities for detecting entanglements in multi-mode systems. Necessary conditions for fully separable, bi-separable and sufficient conditions for fully en...
متن کاملEntanglement purification of gaussian continuous variable quantum states
We describe an entanglement purification protocol to generate maximally entangled states with high efficiencies from two-mode squeezed states or from mixed Gaussian continuous entangled states. The protocol relies on a local quantum nondemolition measurement of the total excitation number of several continuous variable entangled pairs. We propose an optical scheme to do this kind of measurement...
متن کاملQuantum nonlocality obtained from local states by entanglement purification.
We have applied an entanglement purification protocol to produce a single entangled pair of photons capable of violating a Clauser-Horne-Shimony-Holt Bell inequality from two pairs that individually could not. The initial poorly entangled photons were created by a controllable decoherence that introduced complex errors. All of the states were reconstructed using quantum state tomography which a...
متن کاملVerifying multipartite mode entanglement of W states
We construct a method for verifying mode entanglement of N -mode W states. The ideal W state contains exactly one excitation symmetrically shared between N modes, but our method takes the existence of higher numbers of excitations into account, as well as the vacuum state and other deviations from the ideal state. Moreover, our method distinguishes between full N -party entanglement and states ...
