Scalability, Complexity and Reliability in Quantum Information Processing

摘要

This program was a theoretical/experimental 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 theoretical objectives were as follows: (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, fault tolerance and architectures, and quantum and classical complexity classes; and (3) to develop secure primitives for quantum cryptography. The experimental objectives were to develop a 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 the achievement of deterministic control in atom/cavity systems.
