High-Fidelity, Frequency-Flexible Two-Qubit Fluxonium Gates with a Transmon Coupler
Leon Ding, Max Hays, Youngkyu Sung +16
We propose and demonstrate an architecture for fluxonium-fluxonium two-qubit gates mediated by transmon couplers (FTF, for fluxonium-transmon-fluxonium). Relative to architectures…
Extensible circuit-QED architecture via amplitude- and frequency-variable microwaves
Agustin Di Paolo, Catherine Leroux, Thomas M. Hazard +4
We introduce a circuit-QED architecture combining fixed-frequency qubits and microwave-driven couplers. In the appropriate frame, the drive parameters appear as tunable knobs enabl…
Superconducting-semiconducting voltage-tunable qubits in the third dimension
Thomas M. Hazard, Andrew J. Kerman, Kyle Serniak +1
We propose superconducting-semiconducting (super-semi) qubit and coupler designs based on high-quality, compact through-silicon vias (TSVs). An interposer "probe" wafer containing…
Experimental realization of an intrinsically error-protected superconducting qubit
Andras Gyenis, Pranav S. Mundada, Agustin Di Paolo +6
Encoding a qubit in logical quantum states with wavefunctions characterized by disjoint support and robust energies can offer simultaneous protection against relaxation and pure de…
Single-Spin Relaxation in a Synthetic Spin-Orbit Field
F. Borjans, D. M. Zajac, T. M. Hazard +1
Strong magnetic field gradients can produce a synthetic spin-orbit interaction that allows for high fidelity electrical control of single electron spins. We investigate how a field…
A low-disorder Metal-Oxide-Silicon double quantum dot
Jin-Sung Kim, Thomas M. Hazard, Andrew A. Houck +1
One of the biggest challenges impeding the progress of Metal-Oxide-Silicon (MOS) quantum dot devices is the presence of disorder at the Si/SiO interface which interferes with c…
