General parameter-shift rules for quantum gradients
David Wierichs, Josh Izaac, Cody Wang +1
Variational quantum algorithms are ubiquitous in applications of noisy intermediate-scale quantum computers. Due to the structure of conventional parametrized quantum gates, the ev…
Local, Expressive, Quantum-Number-Preserving VQE Ansatze for Fermionic Systems
Gian-Luca R. Anselmetti, David Wierichs, Christian Gogolin +1
We propose VQE circuit fabrics with advantageous properties for the simulation of strongly correlated ground and excited states of molecules and materials under the Jordan-Wigner m…
Training Quantum Embedding Kernels on Near-Term Quantum Computers
Thomas Hubregtsen, David Wierichs, Elies Gil-Fuster +3
Kernel methods are a cornerstone of classical machine learning. The idea of using quantum computers to compute kernels has recently attracted attention. Quantum embedding kernels (…
