Shota Yokoyama,Ryuji Ukai,Seiji Armstrong,Seiji Armstrong,Chanond Sornphiphatphong,Toshiyuki Kaji,Shigenari Suzuki,Jun-ichi Yoshikawa,Hidehiro Yonezawa,Nicolas C. Menicucci,Akira Furusawa +10 more
TL;DR: In this paper, a continuous-variable cluster state containing more than 10,000 entangled modes is deterministically generated and fully characterized, and an efficient scheme for measurement-based quantum computation on this cluster state is presented.
Journal ArticleDOI

Warit Asavanant,Yu Shiozawa,Shota Yokoyama,Baramee Charoensombutamon,Hiroki Emura,Rafael N. Alexander,Shuntaro Takeda,Jun-ichi Yoshikawa,Nicolas C. Menicucci,Hidehiro Yonezawa,Akira Furusawa +10 more
TL;DR: Generating a large-scale two-dimensional continuous-variable cluster state that is compatible with Bosonic error-correcting codes that enable fault-tolerant quantum computation and readily scalable and fault tolerant.
Journal ArticleDOI
Demonstration of a quantum teleportation network for continuous variables
TL;DR: This work reports the experimental realization of a tripartite quantum teleportation network for quantum states of continuous variables (electromagnetic field modes) and demonstrates teleportation of a coherent state between three different pairs in the network, unambiguously demonstrating its tri partite character.
Journal ArticleDOI
Observation of -9 dB quadrature squeezing with improvement of phase stability in homodyne measurement.
TL;DR: The phase stability of homodyne measurement is improved and the intracavity losses are reduced, which show good agreement with theoretical calculations taking account of the phase fluctuation.
Journal ArticleDOI

TL;DR: The best precision for optical-phase tracking has until now been limited by the quantum vacuum fluctuations of coherent light, but this work surpasses this coherent-state limit by using a continuous-wave beam in a phase-squeezed quantum state.
