Demonstrating RFSoC-based Control of a Fully Connected Exchange-Only Qubit
Abigail L. Wessels, M. Garrett Bimstefer, Joseph D. Broz +2
Semiconductor triple-quantum dots (TQDs) are a promising platform for scalable quantum information processing, but the community has so far lacked access to affordable and flexible…
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…
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…
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…
