Time-, spin-, and angle-resolved photoemission spectroscopy with a 1-MHz 10.7-eV pulse laser
Kaishu Kawaguchi, Kenta Kuroda, Z. Zhao +12
We describe a setup of time-, spin-, and angle-resolved photoemission spectroscopy (tr-SARPES) employing a 10.7-eV (=115.6 nm) pulse laser at 1-MHz repetition rate as a probe ph…
Frequency-multiplexed storage and distribution of narrowband telecom photon pairs over a 10-km fiber link with long-term system stability
Ko Ito, Takeshi Kondo, Kyoko Mannami +7
The ability to transmit quantum states over long distances is a fundamental requirement of the quantum internet and is reliant upon quantum repeaters. Quantum repeaters involve ent…
Semiconducting Electronic Structure of the Ferromagnetic Spinel Revealed by Soft-X-Ray Angle-Resolved Photoemission Spectroscopy
Hiroaki Tanaka, Andrei V. Telegin, Yurii P. Sukhorukov +12
We study the electronic structure of the ferromagnetic spinel by soft-x-ray angle-resolved photoemission spectroscopy (SX-ARPES) and first-p…
Single-shot high-resolution identification of discrete frequency modes of single-photon-level optical pulses
Daisuke Yoshida, Mayuka Ichihara, Takeshi Kondo +2
Frequency-multiplexed quantum communication usually requires a single-shot identification of the frequency mode of a single photon . In this paper, we propose a scheme that can ide…
Angle-resolved photoemission spectroscopy
Hongyun Zhang, Tommaso Pincelli, Chris Jozwiak +4
For solid-state materials, the electronic structure, E(k), is critical in determining a crystal's physical properties. By experimentally detecting the electronic structure, the fun…
Coupling of a quantum memory and telecommunication wavelength photons for high-rate entanglement distribution in quantum repeaters
Kyoko Mannami, Takeshi Kondo, Tomoki Tsuno +7
Quantum repeaters are indispensable tools for long-distance quantum communication. However, frequency matching between entangled photon sources and remote quantum memories (QMs) is…
Offset-locking-based frequency stabilization of external cavity diode lasers for long-distance quantum communication
Takuto Miyashita, Takeshi Kondo, Kohei Ikeda +3
Quantum repeaters are required for long-distance quantum communication. For efficient coupling of quantum entangled photon sources with narrow-linewidth quantum memories we perform…
Bulk quantum Hall effect of spin-valley-coupled Dirac fermions in a polar antiferromagnet BaMnSb
H. Sakai, H. Fujimura, S. Sakuragi +16
Unconventional features of relativistic Dirac/Weyl quasi-particles in topological materials are most evidently manifested in the 2D quantum Hall effect (QHE), whose variety is furt…
