Cryogenic characterization of Electrical circuits — •Anupam Kumar, Niklas Lamberty, Thomas Hummel, and Tim J. Bartley — Institute for Photonic Quantum Systems, Paderborn University, Germany

Electrical components are typically optimized for operation near room temperature. Using these components for quantum photonics applications in the future will likely require operation at cryogenic temperatures since the measurement is often performed using superconducting detectors.

In this work, we characterize different electrical components made of various semiconductor platforms such as SiGe, GaAs, and InGaP. These commercial components are characterized at 4K and compared to each other for optimal performance. This allows the design of front-end electrical circuitry for SNSPDs, leading up to a single IC design.
