Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
Spin qubit shuttling between coupled quantum dots with inhomogeneous Landé g-tensors
Zhi-Hai Liu, Xiao-Fei Liu, H. Q. Xu
By utilizing the site-dependent spin quantization axis in semiconductor quantum dot (QD) arrays, shuttling-based spin qubit gates have become an appealing approach to realize scala…
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…
High-precision real-space simulation of electrostatically-confined few-electron states
Christopher R. Anderson, Mark F. Gyure, Sam Quinn +3
In this paper we present a computational procedure that utilizes real-space grids to obtain high precision approximations of electrostatically confined few-electron states such as…
Fast and high-fidelity state preparation and measurement in triple-quantum-dot spin qubits
Jacob Z. Blumoff, Andrew S. Pan, Tyler E. Keating +19
We demonstrate rapid, high-fidelity state preparation and measurement in exchange-only Si/SiGe triple-quantum-dot qubits. Fast measurement integration ( ns) and initialization…
Semiconductor Spin Qubits
Guido Burkard, Thaddeus D. Ladd, John M. Nichol +2
The spin degree of freedom of an electron or a nucleus is one of the most basic properties of nature and functions as an excellent qubit, as it provides a natural two-level system…
Detuning Axis Pulsed Spectroscopy of Valley-Orbital States in Si/SiGe Quantum Dots
Edward H. Chen, Kate Raach, Andrew Pan +16
Silicon quantum dot qubits must contend with low-lying valley excited states which are sensitive functions of the quantum well heterostructure and disorder; quantifying and maximiz…
Split-Gate Cavity Coupler for Silicon Circuit Quantum Electrodynamics
F. Borjans, X. Croot, S. Putz +12
Coherent charge-photon and spin-photon coupling has recently been achieved in silicon double quantum dots (DQD). Here we demonstrate a versatile split-gate cavity-coupler that allo…
Resonant Exchange Operation in Triple-Quantum-Dot Qubits for Spin-Photon Transduction
Andrew Pan, Tyler E. Keating, Mark F. Gyure +5
Triple quantum dots (TQDs) are promising semiconductor spin qubits because of their all-electrical control via fast, tunable exchange interactions and immunity to global magnetic f…
Density Matrix Modeling of Quantum Cascade Lasers without an Artificially Localized Basis: A Generalized Scattering Approach
Andrew Pan, Benjamin A. Burnett, Chi On Chui +1
We derive a density matrix (DM) theory for quantum cascade lasers (QCLs) that describes the influence of scattering on coherences through a generalized scattering superoperator. Th…
