Control and Observation of Quantum Mechanical Systems

Back
Abstract:
In the last few decades, a silent revolution is taking place. The exponential growth in microelectronic processing power has been achieved by ever decreasing the size of integrated circuits. These circuits which integrate electrical, mechanical, and sometimes optical devices, have evolved from silicon revolution. It replaced big complex, costly systems with small, affordable, high performance microsystems. Microsystems are expected to further enable silicon chips to sense, "think", act, and communicate. In essence, to become intelligent machines. Structures of current microsystems are approaching fundamental limits and the next generation of devices might show unexpected properties due to quantum effects and fluctuations. A new research field is developing in which we pursue understanding of basic physics associated with such quantum structures, explore their controllability, and propose new devices. In this talk, we will begin with a summary of engineering problem solving and proceed to discuss the impact of technology on the development of newly emerging discipline of soft computing and computational intelligence. Following an introduction of the historical development of the optical communication system-the photo phone, the evolution of quantum computing will be discussed. The difference between quantum mechanical control systems and classical control systems will be pointed out and the enabling technology of the 21st century: control and sensing of quantum mechanical systems will be introduced to facilitate the design of sensors and actuators of quantum mechanical systems.
