Summary on Grant Application Form
The possibility of quantum algorithms that outperform classical algorithms, the concept of quantum information and the idea that entanglement represents a novel resource are fundamental insights that formed key building blocks in the development of the new field of quantum information science. These ideas have revolutionized our notion of information and computation. However in each of the key areas of quantum entanglement, quantum communication and quantum algorithms the new developments have given rise to significant open questions.The interdisciplinary Bristol theory group, from departments of computer science, mathematics and physics, will address a number of key issues in these areas. This work provides an underpinning theoretical programme for the IRC in quantum information processing. Dynamical aspects of entanglement will be investigated both for interactions of small numbers of systems and for larger collections in interacting particles. We aim to develop new cryptographic protocols for example in the areas of state encryption, key distillation and novel cryptographic primitives. We will investigate the mathematical structure of quauntum algorithms with a view to their generalisation and search for new problems which might gain quantum enhancement. We also plan to design new small-scale experiments demonstrating quantum information processing, for example providing novel tests of fundamental quantum effects, both bi-partite and multi-partite.
