Spectator Errors in Tunable Coupling Architectures
D. M. Zajac, J. Stehlik, D. L. Underwood +9
The addition of tunable couplers to superconducting quantum architectures offers significant advantages for scaling compared to fixed coupling approaches. In principle, tunable cou…
Tunable Coupling Architecture for Fixed-frequency Transmons
J. Stehlik, D. M. Zajac, D. L. Underwood +9
Implementation of high-fidelity two-qubit operations is a key ingredient for scalable quantum error correction. In superconducting qubit architectures tunable buses have been explo…
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…
Shuttling a single charge across a one-dimensional array of silicon quantum dots
A. R. Mills, D. M. Zajac, M. J. Gullans +3
Significant advances have been made towards fault-tolerant operation of silicon spin qubits, with single qubit fidelities exceeding 99.9%, several demonstrations of two-qubit gates…
Strong Coupling of a Single Electron in Silicon to a Microwave Photon
X. Mi, J. V. Cady, D. M. Zajac +2
Silicon is vital to the computing industry due to the high quality of its native oxide and well-established doping technologies. Isotopic purification has enabled quantum coherence…
A Reconfigurable Gate Architecture for Si/SiGe Quantum Dots
D. M. Zajac, T. M. Hazard, X. Mi +2
We demonstrate a reconfigurable quantum dot gate architecture that incorporates two interchangeable transport channels. One channel is used to form quantum dots and the other is us…
