Probing Entanglement and Parameter Sensitivity in QAOA via Quantum Fisher Information
Variational quantum algorithms are widely viewed as a route to near-term quantum advantage, but their performance often depends on a small subset of influential parameters and on how entanglement couples those parameters through the circuit. In a new study published in Quantum Review Letters, a team of researchers use Quantum Fisher Information (QFI) to quantify how the Quantum […]
