As the great Niels Bohr famously remarked "Anyone who is not shocked by Quantum Theory has not understood it". Even today approximately a century after the extended formulation of Quantum Theory, its foundations continue to puzzle and perplex us. The spooky action at a distance of quantum entanglement eludes rational explanation. A quantum cat can be both dead and alive. The reconciliation of the theory with that of gravity remains unsolved. Yet despite these theoretical issues, quantum theory has provided scores of spectacularly accurate measurements and has led to a host of everyday devices used all over the world. This conference will explore the origins, achievements and technological developments from this all pervasive theory.
