Sequential Quantum Teleportation of Optical Coherent States
Hidehiro Yonezawa, Akira Furusawa, Peter van Loock
We demonstrate a sequence of two quantum teleportations of optical coherent states, combining two high-fidelity teleporters for continuous variables. In our experiment, the individ…
Experimental demonstration of quantum teleportation of broadband squeezing
Hidehiro Yonezawa, Samuel L. Braunstein, Akira Furusawa
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…
Experimental Demonstration of Macroscopic Quantum Coherence in Gaussian States
Christoph Marquardt, Ulrik L. Andersen, Gerd Leuchs +4
We witness experimentally the presence of macroscopic coherence in Gaussian quantum states using a recently proposed criterion (E.G. Cavalcanti and M. Reid, Phys. Rev. Lett. 97, 17…
Observation of -9 dB quadrature squeezing with improvement of phase stability in homodyne measurement
Yuishi Takeno, Mitsuyoshi Yukawa, Hidehiro Yonezawa +1
We observe -9.010.14 dB of squeezing and +15.120.14 dB of antisqueezing with a local oscillator phase locked in homodyne measurement. In reference [1], two main factors a…
