Measurements of our first microwave resonators:

a) Optical microscope image of one of the on-chip resonators we fabricated. b) A sample of the spectral response, which is a signature of a resonance. c) The change in the quality factor of a resonator as a function of the number of photons in it hints at the internal mechanisms of quantum decoherence.

Our group is funded by a pair of awards from NSF's QuIC-TAQS program:

Interconnected Superconducting and Color Center Qubits in Silicon Devices

This collaboration with UC Berkley and Virginia Tech aims to establish connectivity between silicon single-photon emitters and superconducting qubits via optical interfaces.

Voltage-Tunable Hybrid Microwave-Acoustic Interconnects for Multi-modal Quantum Memories

This collaboration with NYU, Virginia Tech, Clemson aims to realize a scalable architecture for quantum memories based on mechanical memories and voltage-tunable microwave coupling.
