A system that must get and process large amounts of information to function can be termed complex. UROP/S.B., M.S., and Ph.D. research topics in information and complex systems include: (1.1) Control of noisy, nonlinear systems. Statistical mechanics and nonlinear dynamics supply novel techniques for modeling and controlling noisy, nonlinear systems. Topics include robotics, machine learning, and the characterization and control of systems at the nanoscale. (1.2) Dynamics and thermodynamics of smart heat engines. As Maxwell noted, information and entropy play complementary roles in statistical mechanics. The relation of information processing ability to thermodynamic efficiency is explored in a variety of systems ranging from smart batteries to molecular motors. (1.3) Characterization and control of complex systems. Machines that get and process large amounts of information suffer from glitches and failure modes that simpler machines do not face. Methods from computational complexity theory and axiomatic design are sued to analyze problems of reliability and performance for large systems. Information is mechanical: The way in which systems register and process information is governed by the laws of physics. The creation of novel computing devices involves the interplay between nonlinear dynamics, statistical mechanics, and quantum mechanics. UROP/S.B., M.S., and Ph.D. research topics in mechanics of information processing include: (2.1) Quantum computing. Quantum computers are devices that store and process information on quantum systems such as spins, photons, and atoms. Quantum computation provides a paradigm for information processing that differs fundamentally from ordinary digital computation. Topics include quantum logic devices, error correction, and quantum communications. (2.2) Quantum control. Controlling small systems is difficult: noise, the difficulty of obtaining reliable information, and the paucity of control techniques play a much greater role in microsystems than at the macroscale. Measurement unavoidably perturbs quantum systems, making feedback control problematic. Techniques are developed for controlling and manipulating quantum systems. ---------------- 나의 왼쪽은 너의 옳은쪽이다. :homo sapiens quantum gravitius:mason@kids |
