Time-optimal control of two-level quantum systems by piecewise constant pulses
E. Dionis, D. Sugny
We apply an extension of the Pontryagin Maximum Principle to derive time-optimal controls of two-level quantum systems by means of piecewise constant pulses. Global optimal solutio…

Sub-Harmonic Control of a Fluxonium Qubit via a Purcell-Protected Flux Line
Johannes Schirk, Florian Wallner, Longxiang Huang +21
Protecting qubits from environmental noise while maintaining strong coupling for fast high-fidelity control is a central challenge for quantum information processing. Here, we demo…

Optimal control of a Bose-Eintein Condensate in an optical lattice: The non-linear and two-dimensional cases
E. Dionis, B. Peaudecerf, S. Guérin +2
We numerically study the optimal control of an atomic Bose-Einstein condensate in an optical lattice. We present two generalizations of the gradient-based algorithm, GRAPE, in the…
