Phase and amplitude control of microwave pulse in a linear array of superconducting artificial atoms

摘要: Based on phase controlled electromagnetically induced transparency, we propose a scheme for coherent control and storage of microwave pulse in linear array artificial atoms. In particular, consider the effects amplitude fields driving superconducting atoms attached to one-dimensional transmission line pulse. We show that controlling relative-phase coupling three-level Δ-configuration can yield tunable transparency window, which allows propagation The amplitude-control lower-levels field adds gain signature window. Our results absorption probe is suppressed it gets amplified while propagating through an group velocity considerably reduced as result act memories.
