The Bluefors Dilution Refrigerator as an Integrated Quantum Measurement System

Measurements of quantum devices at millikelvin temperatures take on new importance today because of immediate applications in quantum simulations (Georgescu, Ashhab, & Nori, 2014), quantum sensing (Degen, Reinhard, & Cappellaro, 2017), and the world-wide race to build a fault tolerant quantum computer (Kjaergaard, et al., 2020). Scientists and engineers require integrated measurement systems to perform fast, and accurate characterization of quantum devices. The main measurement challenges are that devices require detection of very weak microwave signals and are exquisitely sensitive to environmental factors. Bluefors systems are often used as a platform for quantum devices as evidenced by more than 200 references (as of March 2021) to the Bluefors system in technical literature that focuses on quantum measurements or qubits. This application note reports a decisive step towards demonstrating a "turn-key" integrated quantum measurement system that requires a vastly reduced number of steps required by the end-user to begin a quantum measurement. This advance is enabled by the integration of a PXI-based quantum measurement system from Keysight Quantum Engineering Solutions (QES) and the Labber instrument control software.
