Rapid quantum ground state preparation via dissipative dynamics
summary
Claims that Lindblad-style dissipative dynamics can prepare ground states from arbitrary initial states (even exponentially small overlap) and proves exponential convergence for gapped quadratic Majorana Hamiltonians with an explicit rate; constructs jump operators using local/quasi-local Pauli or Majorana couplings and a filter f implemented via single-ancilla Hamiltonian simulation; shows numerically that molecular Hamiltonians reach chemical accuracy with universal e^{-t} relaxation for quadratic Hartree–Fock and that bulk Gibbs-type cooling mixes as mixing time ~ log N while TFIM boundary cooling exhibits observed boundary cooling scales ~ N^3; provides tensor-network simulators and perturbative proofs for weakly interacting regimes.
