Nanophotonics devices require an interface between optical fibers and semiconductor chips. Here you see a tapered optical fiber probe that we have fabricated for this purpose.
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.
QE chem lab starts operation.
We are cold! Our first dilution refrigerator gets operational.
Optical tables installed in B260.
Lab renovations is complete.
Group webpage launched!
We have measured the first transmon qubit fabricated in our lab! Here are some characterization data:
Our lab is now part of the Q-NEXT. Funded by DOE, the Q-NEXT's mission is to deliver quantum interconnects and establish a national foundry to provide pristine materials for new quantum devices.
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.
