Phys. Rev. A 79, 050303(R) (2009) [4 pages]Entanglement signature in the mode structure of a single photon
It is shown that entanglement, which is a quantum correlation property of at least two subsystems, is imprinted in the mode structure of a single photon. The photon, which is emitted by two coupled cavities, carries the information on the concurrence of the two intracavity fields. This can be useful for recording the entanglement dynamics of two cavity fields and for entanglement transfer. © 2009 The American Physical Society URL:
