Expressibility, entangling power and quantum average causal effect for causally indefinite circuits

2024 · arXiv (Cornell University)

Parameterized quantum circuits are the core of new technologies such as variational quantum algorithms and quantum machine learning, which makes studying its properties a valuable task. We implement parameterized circuits with definite and indefinite causal …

Benchmarking variational quantum eigensolvers for entanglement detection in many-body Hamiltonian ground states

2025 · AVS Quantum Science

Variational quantum algorithms (VQAs) have emerged in recent years as a promise to obtain quantum advantage. These task-oriented algorithms work in a hybrid loop combining a quantum processor and classical optimization. Using a specific class …
