Driven anti-Bragg subradiant correlations in waveguide quantum electrodynamics

Research output: Contribution to journal › Article › peer-review

Abstract

We study theoretically driven quantum dynamics in periodic arrays of two-level qubits coupled to the waveguide. We demonstrate that strongly subradiant eigenstates of the master equation for the density matrix emerge under strong coherent driving for arrays with the anti-Bragg periods d=λ/4,3λ/4.... This happens even though are no such eigenstates at low driving powers and is directly manifested by long-living quantum correlations between the qubits.
