Typical correlations and entanglement in random MPS and PEPS

Recently it was shown in 关10,11兴 that for localized random vectors, the linear entanglement entropy 共first order of the von Neumann entropy 兲 of one qubit with all the others can

Instead of constructing a ground state at random and then studying the spectral properties of the corresponding local translation-invariant Hamiltonian, what about directly

However, ‘physically relevant’ states of many-body quantum systems, such as ground states of gapped local Hamiltonians, are (conjectured to be) well approximated by so-called

We consider an analog of entanglement-swapping for a set of black boxes with the most general nonlocal correlations consistent with relativity (including correlations which are

Seen from this perspective, the assumption that the laser sources in the quantum random number generators used to choose the measurement settings in a standard Bell experiment [9]

If he can only distinguish two states versus the other two, the correlation shared by the three parties will be bilocal 16 ; if he can choose among two different pairwise groupings
