Two-qutrit quantum Rabi model is integrable under specific conditions, allowing derivation of ground-state phase diagram with level crossings and superradiant quantum phase transition.
Entanglement certification with randomized measurements is the most resource-intensive task among all two-qubit invariants because it requires the maximum number of measurement settings.
Structure-aware VQE ansatze for long-range Ising models cut required circuit layers by 2.5x to 3.8x in non-local regimes while two-qubit gate counts scale quadratically with system size, consistent with the number of Hamiltonian terms.
Multiple Unruh-DeWitt detectors harvest more vacuum entanglement when arranged in specific configurations, with harvested negativity scaling linearly in linear chains.
