Integrated High Field Magnet and Ultra-Low Noise Microwave Measurement Apparatus for Hybrid Quantum Devices
Abstract
This program will integrate two powerful yet typically incompatible experimental capabilities in a single cryogenic setup. High-field magnets (up to 9 Tesla) which are required for spin-based and topological quantum devices will be combined with quantum-limited microwave measurements developed for near-zero field superconducting qubits. This will advance research at the University of Pittsburgh in Majorana-based qubits and one-dimensional quantum wires, as well as high-field tolerant purely superconducting devices based on two-dimensional films of transition metal dichalcogenides. The instrument will be based on an existing dilution refrigerator designated for the development of new collaborative projects. Major new components include a pair of shielded high-field magnets, cryogenic circulators, low-noise cryogenic amplifiers, and room temperature control and readout electronics. Over the 15-year useful lifetime of this instrument it will be used in the training and research of several dozens of students and as a resource for collaborations in quantum information, nanoscience and materials science between Pittsburgh area universities (Carnegie Mellon and Duquesne) as well as supporting national and international collaborations in quantum device engineering.
