Measurement-assisted quantum dynamics control of 5-level system using intense CW-laser fields

摘要

A new quantum control scheme using intense CW-laser fields together with quantum measurement is applied to Kobrak-Rice 5-level (KR5) quantum system. Population dynamics of the KR5 system under frequent measurements is clarified by effective Liouville equation. It is found that one can control the stationary population distribution that appears in t -> infinity limit by varying laser intensities. (c) 2006 Elsevier B.V. All rights reserved.
