Strengthening the quantum data processing inequality for maximal -divergences via unraveling
Marcos Ruibal Ortigueira, Robert de Keijzer, Luke Visser +2
Maximal -divergences, among them the Belavkin--Staszewski relative entropy, are non-increasing under completely positive trace-preserving maps, which is the quantum data process…
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…
Consensus-based qubit configuration optimization for variational algorithms on neutral atom quantum systems
Robert de Keijzer, Luke Visser, Oliver Tse +1
In this work, we report an algorithm that is able to tailor qubit interactions for individual variational quantum algorithm problems. Here, the algorithm leverages the unique abili…
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…
