Quantum optimization

A Monte Carlo Tree Search approach to QAOA: finding a needle in the haystack

The search for quantum algorithms to tackle classical combinatorial optimization problems has long been one of the most attractive yet challenging research topics in quantum computing. In this context, variational quantum algorithms (VQA) are a …

Qudit-native measurement protocol for dynamical correlations using Hadamard tests

Dynamical correlations reveal important out-of-equilibrium properties of the underlying quantum many-body system, yet they are notoriously difficult to measure in experiments. While measurement protocols for dynamical correlations based on Hadamard …
