Single-Shot Fidelity Reveals Hard and Soft Limits: A Universal Yardstick for Photon-Number-Resolving Detectors
Tetsuya Tsuruta, Akio Yoshizawa, Daiji Fukuda
Photon-number-resolving (PNR) detectors are essential for photonic quantum computing, where a single measurement outcome must reliably herald a specific quantum state. However, det…

Direct observation of photon-induced vortices in superconducting films
Takeshi Jodoi, Fuminori Hirayama, Tetsuya Tsuruta +2
Nucleation of vortex-antivortex pairs (VAPs) is believed to play a central role in the photon detection mechanism of superconducting detectors; however, their direct dynamic observ…
