Abstract:Tensor product states (TPS), which enable decomposing the states of large-dimensional Hilbert space in terms of lower-dimensional elementary tensors, are fundamental tools to capture the quantum nature of condensed matter phenomena. Here, we show how TPS can naturally emerge in the synthetic space of operator moments of bosonic systems described by quadratic (non-)Hermitian Hamiltonians. Beyond their theoretical interest, allowing to simulate the many-body physics of nontrivial large-dimensional Hamiltonians, … Show more
