Highly sensitive optical quantum detectors—known as superconducting nanowire single-photon detectors (SNSPDs)—constitute an important key component for the efficient processing and transmission of quantum information.Scalable and high-quality SNSPDs are therefore of fundamental importance for markets such as secure optical data transmission over the Internet via Quantum Key Distribution, quantum networks, and quantum computing. The central objective of the collaborative project is to enhance SNSPDs with respect to their signal-to-noise ratio—that is, to improve their detection quality.This technological advancement is of critical importance for many future applications—such as quantum networks and quantum computing—since, generally speaking, even more precise detectors than those currently available will be required to process quantum data with minimal error. This reduces the need for error correction and ultimately leads to significant cost savings. From a technological perspective, this translates into three core objectives for the consortium: optimizing the design of the detector chips, improving the cleanroom manufacturing processes for the SNSPD chips, and further developing the readout electronics.
