Description
Many emerging experiments in quantum science and fundamental physics require "quantum eyes" that can sense extremely weak optical signals with high fidelity. In this talk, superconducting nanowire–based photon detectors operating in a dual calorimetric mode will be introduced, enabling both sensitive single‑photon detection and energy‑ or photon‑number–discriminating responses within the same device concept. I will outline how these detectors can be tuned between a standard Geiger mode and a calorimetric mode with photon‑number and energy sensitivity, and briefly describe the cryogenic platform at National Taiwan University that we are building for system characterization and future quantum experiments. I will also sketch how such detectors can support a broad range of applications, from quantum optics and quantum communication to precision measurements and searches for new physics.
