Theory and Experimental Demonstration of Wigner Tomography of Unknown Unitary Quantum Gates
Amit Devra, Léo Van Damme, Frederik vom Ende +2
We investigate the tomography of unknown unitary quantum processes within the framework of a finite-dimensional Wigner-type representation. This representation provides a rich visu…

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…

Recoil-free Quantum Gates with Optical Qubits
Zhao Zhang, Léo Van Damme, Marco Rossignolo +11
We propose a scheme to perform optical pulses that suppress the effect of photon recoil by three orders of magnitude compared to ordinary pulses in the Lamb-Dicke regime. We derive…
