Yonezawa, Hidehiro, Braunstein, Samuel L. orcid.org/0000-0003-4790-136X and Furusawa, Akira (2007) Experimental demonstration of quantum teleportation of a squeezed state. Physical Review Letters. Art. No. 110503. ISSN 1079-7114
We demonstrate an unconditional high-fidelity teleporter capable of preserving the broadband entanglement in an optical squeezed state. In particular, we teleport a squeezed state of light and observe -0.8 ± 0.2dB of squeezing in the teleported (output) state. We show that the squeezing criterion translates directly into a sufficient criterion for entanglement of the upper and lower sidebands of the optical field. Thus, this result demonstrates the first unconditional teleportation of broadband entanglement. Our teleporter achieves sufficiently high fidelity to allow the teleportation to be cascaded, enabling, in principle, the construction of deterministic non-Gaussian operations.
