Entanglement Manipulation via Linear Optical Logic
Chuanwei Zhang · arXiv (Cornell University) · 2001
We propose an experimentally feasible scheme for optimal entanglement concentration with a single copy using linear optical devices (polarization beam splitter, quarter wave plate, half wave plate). The scheme relies on the implementation of arbitrary local quantum operations on the polarization of a single photon via linear optical quantum logic. It is universal and feasible in the sense that it requires only one-order Mach-Zehnder interferometer with some half wave plates and quarter wave plates, but it can implement general entanglement concentration. We also analysis deterministic entanglement manipulation and test the non-concentration theorem of a set of entangled pure states using this scheme.
