Catastrophic failure of quantum annealing owing to non-stoquastic Hamiltonian and its avoidance by decoherence

2022 · arXiv (Cornell University)

Quantum annealing (QA) is a promising method for solving combinatorial optimization problems whose solutions are embedded into a ground state of the Ising Hamiltonian. This method employs two types of Hamiltonians: a driver Hamiltonian and …
