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…

Low-Crosstalk, Silicon-Fabricated Optical Waveguides for Laser Delivery to Matter Qubits
Clayton L. Craft, Nicholas J. Barton, Andrew C. Klug +30
Reliable control of quantum information in matter-based qubits requires precisely applied external fields, and unaccounted for spatial cross-talk of these fields between adjacent q…
