Confinement-Tunable Synthetic Gauge Fields and Floquet Topological Phenomena in a Driven Quantum Wire Qubit
The study investigates how driving a spin qubit in a quantum wire with a parabolic confinement potential using a bichromatic field creates a tunable synthetic gauge field. This leads to new Floquet topological effects, including confinement-induced transitions and non-Abelian geometric phases, suggesting these wires are promising for robust topological quantum computing.
