Methods from computational complexity theory and axiomatic design are sued to analyze problems of reliability and performance for large systems. The creation of novel computing devices involves the interplay between nonlinear dynamics, statistical mechanics, and quantum mechanics. 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.
Measurement unavoidably perturbs quantum systems, making feedback control problematic.
Techniques are developed for controlling and manipulating quantum systems.
