Local Hamiltonians Whose Ground States are Hard to Approximate
Lior Eldar, Aram W. Harrow
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 (ent…

Local Hamiltonians with Approximation-Robust Entanglement
Lior Eldar
Quantum entanglement is considered, by and large, to be a very delicate and non-robust phenomenon that is very hard to maintain in the presence of noise, or non-zero temperatures.…
