An eigenstate of the two-level quantum system is identified as a sliding mode. The objective is to design a control law to steer the system's state into the sliding mode domain and then maintain it in that domain when bounded uncertainties exist in the system Hamiltonian. We propose a controller design method using the Lyapunov methodology and periodic projective measurements. In particular, we give conditions for designing such a control law, which can guarantee the desired robustness in the presence of the uncertainties. The sliding mode control method has potential applications to quantum information processing with uncertainties.", "revisions": [ { "version": "v2", "updated": "2011-09-22T11:14:31.000Z" } ], "analyses": { "keywords": [ "two-level quantum system", "control law", "bounded uncertainties", "sliding mode control method", "robust control method" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1009.0558D" } } }
