Quantum Teleportation of the Temporal Fluctuations of Light

A scheme for the teleportation of a beam of light including its temporal fluctuations is proposed. Expressions for the teleported degrees of first- and second-order optical coherence are presented. Teleportation of an antibunched photon stream illustrates the proposal.

Teleportation of photon antibunching: $g_{\mathrm{out}}^{(2)}(\tau )$ plotted for 25 dB line-center squeezing, ${\gamma }_A/{\gamma }_s=5$, ${\gamma }_B/{\gamma }_i=20$, and ${\gamma }_B/{\gamma }_s=10-{10}^{-3}$ [(a)–(d)]; $\Omega =6{\gamma }_i$.
