Quantum Information Processing: From Theory to Experiment

This program was a theory/experiment collaboration focusing on the fundamental need for scalability in the development of quantum information processing. Theory and experiment were connected and interleaved at several levels. The theory objectives were 1) to develop new theoretical tools to enable the implementation of reliable quantum information processing in scalable systems and 2) to characterize the relations between quantum algorithms and architectures, between fault tolerance and architectures, between quantum and classical complexity classes, and to develop secure primitives for quantum cryptography. The experimental objectives were to develop scalable quantum component technology based on gas phase systems using atoms and light fields. Specific experimental goals were scalable implementation of universal quantum logic in optical lattices and achievement of deterministic control in atom/cavity systems.

The general quantum information processing (QIP) in quantum wires is explained. The development of nonlinear and quantum massive optics is introduced. A model of electronic beats and quantum wires is shown. The design of quantum bits, entangle states and the related theory, as well as an experiment to test Bell′s inequality are introduced in details. A method to study QIP in quantum wires is proposed.

Frequency-bin encoding has emerged as a promising approach for fiber- and chip-compatible quantum information processing. We overview the basic theory and experiments, as well as offer perspectives on opportunities for continued advances.
