Landau-Zener-Stückelberg interferometry of a single electron charge qubit
Landau-Zener-Stückelberg interferometry of a single electron charge qubit
We perform Landau-Zener-Stuckelberg interferometry on a single electron GaAs charge qubit by repeatedly driving the system through an avoided crossing. We observe coherent destruction of tunneling, where periodic driving with specific amplitudes inhibits current flow. We probe the quantum dot occupation using a charge sensor, observing oscillations in the qubit …
