Superconducting Nanowire Single-Photon Detectors (SNSPDs) are highly sensitive devices used to detect single photons with high efficiency and low timing jitter. These detectors utilize superconducting nanowires that exhibit a transition from a superconducting state to a resistive state when a photon is absorbed, allowing for precise measurement of light at the quantum level. SNSPDs are crucial for applications in quantum information processing, quantum communication, and astrophysics, where detecting individual photons is essential.
congrats on reading the definition of SNSPDs. now let's actually learn it.
