Eigenbasis of the Evolution Operator of 2-Tessellable Quantum Walks

Yusuke Higuchi, Renato Portugal, Iwao Sato +1

Staggered quantum walks on graphs are based on the concept of graph tessellation and generalize some well-known discrete-time quantum walk models. In this work, we address the clas…

Periodicity for the Fourier quantum walk on regular graphs

Kei Saito

Quantum walks determined by the coin operator on graphs have been intensively studied. The typical examples of coin operator are the Grover and Fourier matrices. The periodicity of…

Uniform stationary measure of space-inhomogeneous quantum walks in one dimension

Yusuke Ide, Norio Konno, Daichi Nakayama

The discrete-time quantum walk (QW) is a quantum version of the random walk (RW) and has been widely investigated for the last two decades. Some remarkable properties of QW are wel…

A compact frequency-stabilized pump laser for wavelength conversion in long-distance quantum communication

Kohei Ikeda, Yusuke Hisai, Kazumichi Yoshii +3

We demonstrate a compact frequency-stabilized laser at 1064 nm using Doppler-free saturation absorption spectroscopy of molecular iodine. The achieved laser frequency stability and…

Two-step frequency conversion for connecting distant quantum memories by transmission through an optical fiber

Shuhei Tamura, Kohei Ikeda, Kotaro Okamura +4

Long-distance quantum communication requires entanglement between distant quantum memories. For this purpose, photon transmission is necessary to connect the distant memories. Here…

Ultrabright narrow-band telecom two-photon source for long-distance quantum communication

Kazuya Niizeki, Kohei Ikeda, Mingyang Zheng +7

We demonstrate an ultrabright narrow-band two-photon source at the 1.5 -μm telecom wavelength for long-distance quantum communication. By utilizing a bow-tie cavity, we obtain a ca…

A new time-series model based on quantum walk

Norio Konno

The quantum walk (QW) was introduced as a quantum counterpart of the classical random walk. A number of non-classical properties of the QW have been shown, e.g., ballistic spreadin…
