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…
Pulse family optimization for parametrized quantum gates using spectral clustering
Robert de Keijzer, Jurgen Snijders, André Carvalho +1
Parametrized gate circuits are used in plentiful applications in the current NISQ era of quantum computing. These parametrized gates are chiefly implemented using analytically foun…
