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…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +255
Commercially-relevant quantum computers will require large numbers of high-performing qubits that can be manufactured, integrated, and controlled at scale. Silicon exchange-only (E…
High fidelity state preparation, quantum control, and readout of an isotopically enriched silicon spin qubit
A. R. Mills, C. R. Guinn, M. M. Feldman +6
Quantum systems must be prepared, controlled, and measured with high fidelity in order to perform complex quantum algorithms. Control fidelities have greatly improved in silicon sp…
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…
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…
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…
