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…
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…
