Uncovering Latent Structures in Robust Pulse Sequences: A Model-Based Reinforcement Learning Approach for Adaptable Quantum Control
Tobias Kiermeyer, Thomas Heydenreich, Léo Van Damme +3
Real-time adaptive control of quantum systems requires rapid generation of robust, high-fidelity pulses across a continuous range of operating conditions. Standard optimization alg…
Superconducting Qubit Gates Robust to Parameter Fluctuations
Emily Wright, Leo Van Damme, Niklas J. Glaser +14
State-of-the-art single-qubit gates on superconducting transmon qubits can achieve the fidelities required for error-corrected computations. However, parameter fluctuations due to…
Motion-Insensitive Time-Optimal Control of Optical Qubits
Léo Van Damme, Zhao Zhang, Amit Devra +2
In trapped-atom quantum computers, high-fidelity control of optical qubits is challenging due to the motion of atoms in the trap. If not corrected, the atom motion gets entangled w…
Application of the Small Tip-Angle approximation in the Toggling Frame for the design of analytic robust pulses in Quantum Control
L. Van Damme, D. Sugny, S. J. Glaser
We apply the Small Tip-Angle Approximation in the Toggling Frame in order to analytically design robust pulses against resonance offsets for state to state transfer in two-level qu…
Geometric Origin of the Tennis Racket Effect
P. Mardesic, L. Van Damme, G. J. Gutierrez Guillen +1
The tennis racket effect is a geometric phenomenon which occurs in a free rotation of a three-dimensional rigid body. In a complex phase space, we show that this effect originates…
Time-optimal selective pulses of two uncoupled spin 1/2 particles
L. Van Damme, Q. Ansel, S. J. Glaser +1
We investigate the time-optimal solution of the selective control of two uncoupled spin 1/2 particles. Using the Pontryagin Maximum Principle, we derive the global time-optimal pul…
