Query: Fast electron spin flips via strong subcycle electric excitation   An important goal in quantum information processing is to reduce the duration
of quantum-logical operations. Motivated by this, we provide a theoretical
analysis of electrically induced fast dynamics of a single-electron spin-orbit
qubit. We study the example of a one-dimensional quantum dot with Rashba
spin-orbit interaction and harmonic driving, and focus on the case of strong
driving, when the real-space oscillation amplitude of the driven electron is
comparable to the width of its wave function. We provide simple approximate
analytical relations between the qubit Larmor frequency, the shortest
achievable qubit-flip time, and the driving amplitude required for the shortest
achievable qubit flip. We find that these relations compare well with results
obtained from numerical simulations of the qubit dynamics. Based on our
results, we discuss practical guidelines to maximize speed and quality of
electric single-qubit operations on spin-orbit qubits.
