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…
Leakage-protected idle operation of a triangular exchange-only spin qubit
Joseph D. Broz, Jesse C. Hoke, Edwin Acuna +1
We characterize the coherence of a triangular exchange-only (EO) spin qubit operated at a leakage-protected idle (LPI) point. The triangular geometry enables independent control of…
Demonstration of an always-on exchange-only spin qubit
Joseph D. Broz, Jesse C. Hoke, Edwin Acuna +1
In conventional exchange-only (EO) spin qubit demonstrations, quantum gates have been implemented using sequences of individually pulsed pairwise exchange interactions with only on…
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…
