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…
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…
