The s-ordered phase-sum and phase-difference distributions are considered for Bell-like superpositions of two-mode coherent states. The distributions are sensitive, respectively, to the sum and difference of the phases of the entangled coherent states. They show loss of information about the entangled state and may take on negative values for some orderings s.
متن کاملGeneration of phase-coherent states
Optical processes taking place in (2) media involve three light waves, yielding to a considerably rich variety of nonlinear phenomena, both in the semi-classical [1] and in the quantum domain [2]. The quantum statistical properties of the radiation coming out from such interactions have attracted much attention (see for example Refs. [3,4]). Squeezing, anti-bunching and entanglement have been p...
متن کاملMultipartite entangled coherent states
We propose a scheme for generating multipartite entangled coherent states via entanglement swapping, with an example of a physical realization in ion traps. Bipartite entanglement of these multipartite states is quantified by the concurrence. We also compute multipartite entanglement for certain systems. Finally we establish that these results for entanglement can be applied to more general mul...
متن کاملTopological phase for entangled two-qubit states.
Entangled states play a crucial role in quantum physics, ranging from fundamental aspects to quantum information processing. We show here that entangled two-qubit states can also be used to characterize unambiguously the subtlety of the SO(3) rotation group topology. The well known two distinct families of path in this group are put in one-to-one correspondence with cyclic evolutions of these e...
متن کاملPurification of entangled coherent states
We suggest an entanglement purification scheme for mixed entangled coherent states using 50-50 beam splitters and photodetectors. This scheme is directly applicable for mixed entangled coherent states of the Werner type, and can be useful for general mixed states using additional nonlinear interactions. We apply our scheme to entangled coherent states decohered in a vacuum environment and find ...
