Quantum Dots / Spin Qubits
Shannon Harvey
Spin qubits in semiconductor quantum dots represent a prominent family of solid-state qubits in the effort to build a quantum computer. They are formed when electrons or holes are…
Character of the "normal state" of the nickelate superconductors
Kyuho Lee, Bai Yang Wang, Motoki Osada +10
The occurrence of superconductivity in proximity to various strongly correlated phases of matter has drawn extensive focus on their normal state properties, to develop an understan…
Evidence for nodal superconductivity in infinite-layer nickelates
Shannon P. Harvey, Bai Yang Wang, Jennifer Fowlie +5
Infinite-layer nickelates present a new family of potential unconventional superconductors. A key open question is the superconducting pairing symmetry. We present low-temperature…
Parametric longitudinal coupling between a high-impedance superconducting resonator and a semiconductor quantum dot singlet-triplet spin qubit

Danfeng Li, Bai Yang Wang, Kyuho Lee +5
We report the phase diagram of NdSrNiO infinite layer thin films grown on SrTiO. A superconducting dome spanning is found, remarkably similar…
Readout Of Singlet-Triplet Qubits At Large Magnetic Field Gradients
Lucas A. Orona, John M. Nichol, Shannon P. Harvey +5
Visibility of singlet-triplet qubit readout is reduced to almost zero in large magnetic field gradients due to relaxation processes. Here we present a new readout technique that is…

We present efficient methods to reliably characterize and tune gate-defined semiconductor spin qubits. Our methods are designed to target the tuning procedures of semiconductor dou…
Coupling Two Spin Qubits with a High-Impedance Resonator
S. P. Harvey, C. G. L. Bøttcher, L. A. Orona +3
Fast, high-fidelity single and two-qubit gates are essential to building a viable quantum information processor, but achieving both in the same system has proved challenging for sp…
High-fidelity entangling gate for double-quantum-dot spin qubits
John M. Nichol, Lucas A. Orona, Shannon P. Harvey +4
Electron spins in semiconductors are promising qubits because their long coherence times enable nearly 10^9 coherent quantum gate operations. However, developing a scalable high-fi…
