Microwave loss of van der Waals dielectrics in the low-temperature, single-photon regime

ORAL

Abstract

Microwave dielectric loss – due to interaction between the electromagnetic field and spurious two-level-systems (TLS) – constitutes one of the main sources of decoherence in superconducting quantum circuits. Researches have shown the loss occurs in the bulk of dielectrics as well as of the many interfaces of circuit elements.

Hexagonal boron nitride (hBN), an insulating 2-D(van der Waals) material that features an essentially defect-free bulk and atomically flat surfaces through mechanical exfoliation, may be used to build high-quality Josephson elements and qubit capacitors. We study hBN in the microwave regime via lateral capacitive coupling and parallel plate capacitors. In the single-photon limit, the extracted quality factor of hBN is bounded below at ~ 200,000. Beyond hBN, this measurement technique can also be used to explore new material platforms for superconducting technologies.
