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…

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…

A flexible design platform for Si/SiGe exchange-only qubits with low disorder

Wonill Ha, Sieu D. Ha, Maxwell D. Choi +14

Spin-based silicon quantum dots are an attractive qubit technology for quantum information processing with respect to coherence time, control, and engineering. Here we present an e…

Detuning Axis Pulsed Spectroscopy of Valley-Orbital States in Si/SiGe Quantum Dots

Edward H. Chen, Kate Raach, Andrew Pan +16

Silicon quantum dot qubits must contend with low-lying valley excited states which are sensitive functions of the quantum well heterostructure and disorder; quantifying and maximiz…
