Wiring the Quantum Future: Developing Interconnects for Superconducting Qubits - M. Mirhosseini

10/20/2023 - KNI-Wheatley Scholar Lecture
Mohammad Mirhosseini, Assistant Professor of Electrical Engineering and Applied Physics


Mohammad Mirhosseini has been selected as the 2022 KNI-Wheatley Scholar in Nanoscience for his proposal to develop on-chip transducers that provide optical interconnects for superconducting qubits, one of the leading platforms for quantum computers.

Mirhosseini's project will focus on fabricating MEMS transducers that are embedded with optomechanical devices to form a microwave-optical frequency converter to allow for extremely low acoustic and microwave loss tangents. The fabrication of such devices will, in large part, take place using instrumentation in the KNI Lab, and will then be tested in a dilution refrigerator at Mirhosseini’s lab.

Mirhosseini's work will contribute to expanding the knowledge base within KNI and at Caltech by developing recipes for depositing high-quality metal nitride films of NbN, TiN, and NbTiN. Beyond the intended areas of application in quantum computing, this capability has the potential to benefit other research groups that work on single-photon detection (SNSPDs), amplifiers for dark matter search, mm-wave detectors for astronomy, and plasmonics.

The KNI-Wheatley Scholar in Nanoscience was established in 2016 as a result of a generous endowment from Caltech alumni Chuck Wheatley and his wife Judy. This new initiative provides $25,000 of seed funding to one tenure-track faculty member selected among candidates nominated by Division Chairs and the KNI Board members at Caltech. Early stage proof-of-concept demonstrations are often difficult to support. As envisioned, this unrestricted funding will allow junior faculty in nanoscience the flexibility to pursue novel research ideas.
