Superconducting nanowire single-photon detectors: A perspective on evolution, state-of-the-art, future developments, and applications (2021, background): “81 Since SNSPDs typically cover areas of hundreds of square micro-meters and the electrical signal propagates through the detector with ﬁnite speed, photons detected at different locations generate detection pulses that reach the readout circuit at different times, leading to a geometrical jitter.”
