Complexity from genuine non-Gaussian entanglement: quantum correlations beyond Hong-Ou-Mandel
Quantum state tomography requires exponential copies due to complex correlations. Generalizing the Hong-Ou-Mandel effect, we establish a resource theory for non-Gaussian entanglement, showing polynomial scaling for learning free states and exponential scaling for resource states. .
