Local Hamiltonians Whose Ground States Are Hard to Approximate
Ground states of local Hamiltonians can be generally highly entangled: Any quantum circuit that generates them (even approximately) must be sufficiently deep to allow coupling (entanglement) between any pair of qubits. Until now this property was not known to be robust - the marginals of such states...
