Pulse-Gated Quantum-Dot Hybrid Qubit

Develops nonadiabatic pulse-gated control for the three-electron quantum-dot hybrid qubit.

Key Results

Uses level anticrossings to decompose logical control into fast charge-like transitions.
Provides closed-form one- and two-qubit pulse sequences with sub-nanosecond elementary steps.
Treats a three-electron double quantum dot, not a triple-dot device.
