Emergent-Coupling-Based Ansatz Evaluated on a Superconducting Quantum Processor
Alina Joch, Kevin Lively, Benedikt Fauseweh
The performance of the variational quantum eigensolver depends critically on the choice of ansatz. In this work, we experimentally evaluate the emergent-coupling-based ansatz (ECBA…

Entanglement-informed Construction of Variational Quantum Circuits
Alina Joch, Götz S. Uhrig, Benedikt Fauseweh
The Variational Quantum Eigensolver (VQE) is a promising tool for simulating ground states of quantum many-body systems on noisy quantum computers. Its effectiveness relies heavily…
