Generation and characterization of resource state for nonlinear cubic phase gate
Mitsuyoshi Yukawa, Kazunori Miyata, Hidehiro Yonezawa +3
Unitary non-Gaussian nonlinearity is one of the key components required for quantum computation and other developing applications of quantum information processing. Sufficient oper…
Generating superposition of up-to three photons for continuous variable quantum information processing
Mitsuyoshi Yukawa, Kazunori Miyata, Takahiro Mizuta +4
We develop an experimental scheme based on a continuous-wave (cw) laser for generating arbitrary superpositions of photon number states. In this experiment, we successfully generat…
Experimental demonstration of coherent feedback control on optical field squeezing
Sanae Iida, Mitsuyoshi Yukawa, Hidehiro Yonezawa +2
Coherent feedback is a non-measurement based, hence a back-action free, method of control for quantum systems. A typical application of this control scheme is squeezing enhancement…
Experimental generation of four-mode continuous-variable cluster states
Mitsuyoshi Yukawa, Ryuji Ukai, Peter van Loock +1
Continuous-variable Gaussian cluster states are a potential resource for universal quantum computation. They can be efficiently and unconditionally built from sources of squeezed l…
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…
