"Multipartite entanglement in the optical frequency comb of a depleted-pump optical parametric oscillator"
ABSTRACT:
The generation of massively entangled states is of great interest for quantum information. For quantum communication, multiparty quantum teleportation and quantum secret sharing are good examples. In this talk I will explain about the generation of multipartite continuous-variable entanglement in a single optical parametric oscillator (OPO) well above threshold. In this system, the multipartite entanglement is mediated between independent pairs of two-mode squeezed, bipartite entangled, OPO fields by way of the quantum dynamics of the strongly depleted pump field. We verify the multipartite nature of the entanglement by evaluating the van Loock-Furusawa inequalities.
