The Boulder Cryogenic Quantum Testbed (BCQT) is a joint initiative between NIST and the University of Colorado Boulder that aims to develop and implement standard protocols for measuring the performance characteristics of superconducting microwave resonators used in quantum computing circuits. The project focuses on improving the accuracy, precision, and reproducibility of performance measurements, particularly at millikelvin temperatures and single photon powers.
The BCQT serves as a resource for academic and industry quantum research groups, providing a well-characterized cryogenic environment for measuring superconducting microwave resonators. The project has developed open-source methods and toolkits for data acquisition and analysis, and has conducted research on various aspects of resonator design and measurement techniques, including asymmetric resonance fitting, cryogenic calibration, and quasiparticle effects.
The BCQT measurement platform is available to address the significant microwave loss measurement needs of the growing quantum computing industry, and the project has developed experimental capability for performing high-throughput, accurate measurements of superconducting microwave loss at single photon powers and millikelvin temperatures.
