no code implementations2 Jun 2021 Thomas Hubregtsen, Frederik Wilde, Shozab Qasim, Jens Eisert

A popular set of optimization methods work on the estimate of the gradient, obtained by means of circuit evaluations.

Training Quantum Embedding Kernels on Near-Term Quantum Computers

1 code implementation5 May 2021 Thomas Hubregtsen, David Wierichs, Elies Gil-Fuster, Peter-Jan H. S. Derks, Paul K. Faehrmann, Johannes Jakob Meyer

Quantum embedding kernels (QEKs) constructed by embedding data into the Hilbert space of a quantum computer are a particular quantum kernel technique that allows to gather insights into learning problems and that are particularly suitable for noisy intermediate-scale quantum devices.

Evaluation of Parameterized Quantum Circuits: on the relation between classification accuracy, expressibility and entangling capability

1 code implementation22 Mar 2020 Thomas Hubregtsen, Josef Pichlmeier, Patrick Stecher, Koen Bertels

Quantum Machine Learning, and Parameterized Quantum Circuits in a hybrid quantum-classical setup in particular, could bring advancements in accuracy by utilizing the high dimensionality of the Hilbert space as feature space.
