Non-Hermitian Quantum Annealing and Superradiance
Alexander I. Nesterov, Gennady P. Berman, Fermín Aceves de la Cruz +1
We consider the non-Hermitian quantum annealing for the one-dimentional Ising spin chain, and for a large number of qubits. We show that the annealing time is significanly reduced…

Non-Hermitian Quantum Annealing in the Antiferromagnetic Ising Chain
Alexander I. Nesterov, Gennady P. Berman, Juan C. Beas Zepeda +1
A non-Hermitian quantum optimization algorithm is created and used to find the ground state of an antiferromagnetic Ising chain. We demonstrate analytically and numerically (for up…

Non-Hermitian Quantum Annealing in the Ferromagnetic Ising Model
Alexander I. Nesterov, Juan Carlos Beas Zepeda, Gennady P. Berman
We developed a non-Hermitian quantum optimization algorithm to find the ground state of the ferromagnetic Ising model with up to 1024 spins (qubits). Our approach leads to signific…
