Photonic Quantum Receiver Attaining the Helstrom Bound
Aakash Warke, Janis Nötzel, Kan Takase +6
We propose an efficient decomposition scheme for a quantum receiver that attains the Helstrom bound in the low-photon regime for discriminating binary coherent states. Our method,…
Perspective: Toward large-scale fault-tolerant universal photonic quantum computing
Shuntaro Takeda, Akira Furusawa
Photonic quantum computing is one of the leading approaches to universal quantum computation. However, large-scale implementation of photonic quantum computing has been hindered by…
Time-Domain Multiplexed 2-Dimensional Cluster State: Universal Quantum Computing Platform
Warit Asavanant, Yu Shiozawa, Shota Yokoyama +8
Quantum computation promises applications that are thought to be impossible with classical computation. To realize practical quantum computation, the following three properties wil…
On-demand photonic entanglement synthesizer
Shuntaro Takeda, Kan Takase, Akira Furusawa
Quantum information protocols require various types of entanglement, such as Einstein-Podolsky-Rosen (EPR), Greenberger-Horne-Zeilinger (GHZ), and cluster states. In optics, on-dem…
All-optical storage of phase-sensitive quantum states of light
Yosuke Hashimoto, Takeshi Toyama, Jun-ichi Yoshikawa +6
We experimentally demonstrate storage and on-demand release of phase-sensitive, photon-number superposition states of the form for an optical quant…
Schrödinger's cat in an optical sideband
Takahiro Serikawa, Jun-ichi Yoshikawa, Shuntaro Takeda +4
We propose a method to subtract a photon from a double sideband mode of continuous-wave light. The central idea is to use phase modulation as a frequency sideband beamsplitter in t…
