We consider the non-Hermitian quantum annealing (NQA) for a onedimensional Ising spin chain, and for a large number of qubits. We show that the annealing time is significantly reduced for the non-Hermitian quantum algorithm in comparison with the Hermitian one. We optimize a performance of the NQA, and demonstrate the relation of the NQA with the superradiance transition in this system.
