Spin singlets are useful
Silas Hoffman, Edward H. Chen, Matthew Brooks +6
We evaluate the utility of the spin-zero manifold of an exchange-coupled array of spins for tasks in quantum computation and quantum simulation. Since pairs of electrons can be…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +256
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…
Randomized Benchmarking with Synthetic Quantum Circuits
Yale Fan, Riley Murray, Thaddeus D. Ladd +2
Noise characterization methods such as randomized benchmarking (RB) are critical for the development of scalable quantum computers. Modern RB protocols for multiqubit systems extra…
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…
Two-dimensional Si spin qubit arrays with multilevel interconnects
Sieu D. Ha, Edwin Acuna, Kate Raach +26
The promise of quantum computation is contingent upon physical qubits with both low gate error rate and broad scalability. Silicon-based spins are a leading qubit platform, but dem…
Schrödinger cat states of a nuclear spin qudit in silicon
Xi Yu, Benjamin Wilhelm, Danielle Holmes +17
High-dimensional quantum systems are a valuable resource for quantum information processing. They can be used to encode error-correctable logical qubits, which has been demonstrate…
