Composition-based phase stability model for multicomponent metal alloys
Jay C. Spendlove, Bryan H. Fong, John H. Martin +4
The vastness of the space of possible multicomponent metal alloys is hoped to provide improved structural materials but also challenges traditional, low-throughput materials design…
Full-permutation dynamical decoupling in triple-quantum-dot spin qubits
Bo Sun, Teresa Brecht, Bryan Fong +20
Dynamical decoupling of spin qubits in silicon can enhance fidelity and be used to extract the frequency spectra of noise processes. We demonstrate a full-permutation dynamical dec…
Universal logic with encoded spin qubits in silicon
Aaron J. Weinstein, Matthew D. Reed, Aaron M. Jones +20
Qubits encoded in a decoherence-free subsystem and realized in exchange-coupled silicon quantum dots are promising candidates for fault-tolerant quantum computing. Benefits of this…
Magnetic Gradient Fluctuations from Quadrupolar Ge in Si/SiGe Exchange-Only Qubits
J. Kerckhoff, B. Sun, B. H. Fong +14
We study the time-fluctuating magnetic gradient noise mechanisms in pairs of Si/SiGe quantum dots using exchange echo noise spectroscopy. We find through a combination of spectral…
Randomized Benchmarking as Convolution: Fourier Analysis of Gate Dependent Errors
Seth T. Merkel, Emily J. Pritchett, Bryan H. Fong
We show that the Randomized Benchmarking (RB) protocol is a convolution amenable to Fourier space analysis. By adopting the mathematical framework of Fourier transforms of matrix-v…
Randomized Benchmarking, Correlated Noise, and Ising Models
Bryan H. Fong, Seth T. Merkel
We compute the expected randomized benchmarking sequence fidelity for a system subject to Gaussian time-correlated noise. For single qubit benchmarking we show that the expected se…
