Bootstrapping Quantum Hamiltonians with Symmetry

Author(s): Michael G. Scheer We describe a semidefinite relaxation method which finds lower bounds to the ground state energy of a quantum Hamiltonian subject to Hermitian linear constraints along with approximations of ground state expectation values. We show that symmetry can be used to significantly reduce the computational … [Phys. Rev. Lett. 136, 246501] Published Wed Jun 17, 2026
