First Passage Times for Continuous Quantum Measurement Currents
Michael J. Kewming, Anthony Kiely, Steve Campbell +1
The First Passage Time (FPT) is the time taken for a stochastic process to reach a desired threshold. In this letter we address the FPT of the stochastic measurement current in the…

Universally Robust Quantum Control
Pablo M. Poggi, Gabriele De Chiara, Steve Campbell +1
We study the robustness of the evolution of a quantum system against small uncontrolled variations in parameters in the Hamiltonian. We show that the fidelity susceptibility, which…
