Quantum State Restoration and Single-Copy Tomography for Ground States of Hamiltonians

Quantum State Restoration and Single-Copy Tomography for Ground States of Hamiltonians

Given a single copy of an unknown quantum state, the no-cloning theorem limits the amount of information that can be extracted from it. Given a gapped Hamiltonian, in most situations it is impractical to compute properties of its ground state, even though in principle all the information about the g...
