Abstract:Entanglement verification and measurement is essential for experimental tests of quantum mechanics and also for quantum communication and information science. Standard methods of verifying entanglement in a bipartite mixed state require detection of both particles and involve coincidence measurement. We present a method that enables us to verify and measure entanglement in a twophoton mixed state without detecting one of the photons, i.e., without performing any coincidence measurement or postselection. We con… Show more
