The Quantum Electronics Group at NIST has two main goals: conducting fundamental research and developing advanced readout technology for quantum sensors.
For their first objective, they’re using their expertise in superconducting materials and devices to study weak signal detection and loss mechanisms in superconducting devices. This includes the Boulder Cryogenic Quantum Testbed (BCQT) project, which aims to create standard measurement protocols for superconducting microwave resonators used in quantum computing circuits, especially at extremely low temperatures and single photon power levels.
Their second objective focuses on developing readout technology for arrays of cryogenic and quantum sensors. This involves designing low-noise amplifiers and multiplexing circuits optimized for sensors developed within NIST and the broader community. To support widespread adoption of this technology, they’re also designing and building custom room-temperature electronics needed for end-to-end readout with these systems.
