Fidelity Relations in an Array of Neutral Atom Qubits -- Experimental Validation of Control Noise
Deon Janse van Rensburg, Robert de Keijzer, Rogier Venderbosch +5
Noise is a hindering factor for current-era quantum computers. In this study, we experimentally validate the theoretical relationships between amplitude noise of the control signal…

Quantum relative entropy for unravelings of master equations
Marcos Ruibal Ortigueira, Robert de Keijzer, Luke Visser +2
This work explores connections between the quantum relative entropy of two faithful states (i.e. full-rank density matrices) and the Kullback-Leibler divergences of classic…

Fidelity-Enhanced Variational Quantum Optimal Control
Robert de Keijzer, Luke Visser, Oliver Tse +1
Creating robust quantum operations is a major challenge in the current noisy intermediate-scale quantum computing era. Recently, the importance of noise-resilient control methods h…
