Behaviour analysis and control of quantum systems driven by non classical inputs Abolghasem Daeichian a daiechian@ec iut ac ir March 2014 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree Ph D Language Persian Supervisors Prof Farid Sheikholeslam sheikh@cc iut ac ir Advisor Prof Matthew R James matthew james@anu edu au Assist Prof Hamidreza Koofigar koofigar@eng ui ac ir Graduate coordinator Assoc Prof Mohammadali Khosravifard khosravi@cc iut ac ir Abstract This dissertation could be divided into three parts First part is devoted to represent the fundamental role of quantum control in the generation of quantum technology The grounds and materials of quantum control is broadly surveyed including some topics such as modeling controllability quantum networks quantum filtering open loop and close loop control In the second part a basic question in control engineering is answered which is how a system responds to the different inputs This question is addressed by estimating the system state using quantum filtering for a two level quantum system driven by various inputs including vacuum state multimode single photon and superposition of coherent states The purity of state is also considered and its dynamic is derived as another parameter of system behavior Pure states represent quantum states of maximal information and they are desired in many applications Finally an algorithm is presented to control a quantum system based on feedback The controller design is based on derivation of closed loop stochastic Schr dinger equation and satisfying a stabilization condition which is defined The proposed method is applied to steers the state of two level quantum system from any initial state into any desired state The simulation results show the validity of the proposed method Keywords quantum feedback control behaviour of quantum system purity of state of quantum system multi mode single photon superposition of coherent states stochastic Schr dinger equation Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan Iran Department of Engineering Australian National University Canberra Australia Department of Electrical Engineering University of Isfahan Isfahan Iran
