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…

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…

Coherent control of a triangular exchange-only spin qubit
Edwin Acuna, Joseph D. Broz, Kaushal Shyamsundar +14
We demonstrate coherent control of a three-electron exchange-only spin qubit with the quantum dots arranged in a close-packed triangular geometry. The device is tuned to confine on…
