High-fidelity continuous-variable quantum teleportation toward multi-step quantum operations
Mitsuyoshi Yukawa, Hugo Benichi, Akira Furusawa
The progress in quantum operations of continuous-variable (CV) schemes can be reduced to that in CV quantum teleportation. The fidelity of quantum teleportation of an optical setup…
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…
