Extraction of Singlet States from Noninteracting High-Dimensional Spins
arXiv:0710.3855 · doi:10.1103/PhysRevLett.100.150501
Abstract
We present a scheme for the extraction of singlet states of two remote particles of arbitrary quantum spin number. The goal is achieved through post-selection of the state of interaction mediators sent in succession. A small number of iterations is sufficient to make the scheme effective. We propose two suitable experimental setups where the protocol can be implemented.
