Department of Trade and Industry, Office of Science and Technology (May 2002)
This report offers to UK Government the considered views of a group of academic and industry experts on the steps that need to be taken if the UK is to build on its current investments in nanotechnologyresearch and become a world class player in nanotechnology applications. It gives a realistic assessment of where we stand in relation to major industrial competitors in realising the potential of this fundamentally new approach to manufacturing. This report makes it quite clear that in order to keep pace with competitor nations it is necessary to recast the scale and nature of nanotechnology activities.

Quantum Mechanics | | Local variant that bypasses Bell's Criterion
J Campbell (November 2000)
This paper attempts to trace a thread running through four separate areas of research into the foundations of fundamental physics, viz. the EPR-type experiments used to test out the predictions of Quantum Theory; the relationship between particles and antiparticles; the implications of Special Relativity and Quantum Theory for hypothesised tachyonic waves; and the effect on light of travelling thru a transmission medium. In this I hope to shed some light on a basic problem with Quantum Theory from its outset - that of its non local nature. (A local interpretation requires changes to a system to be communicated between components by physical processes).

The recent resurgence of activity in molecular electronics, outlined in this review, has evolved through a number of scientific and economic drivers. This can be partially ascribed to developments in nanoscale science and technology such as new fabrication methods and probes that enable individual molecules or small numbers to be connected into actual test devices.

A Konstadopoulou, J. M. Hollingworth, et al, University of Liverpool (November 2000)
A ring made from a Josephson array in the insulating phase is considered. The ring contains a `dual Josephson junction' (Josephson junction for vortices). External non-classical electromagnetic fields are coupled to the device and interact with the vortices that circulate the ring. The time evolution of this two-mode fully quantum mechanical system is studied. The effect of the quantum statistics of the photons on the quantum statistics of the vortices is discussed. The entanglement between the two systems is quantified. Paper from

J G Rarity, P Gorman and P R Tapster, DERA (November 2000)
Here we discuss the first tentative steps to an optically based system for uploading keys to remote platforms using polarisation encoding of weak pulses of light. This method relies on the rules of physics, those of quantum mechanics, to guarantee the absolute security of key generation and exchange and is known as quantum cryptography.

R E Palmer, University of Birmingham (November 2000)
The aim of one day building an operational quantum computer, which follows naturally from the exciting recent theoretical advances in this field, places exceptionally severe demands on device fabrication. Nanotechnology - the exploitation of nanometre-scale structures - may provide a toolbox which allows such a goal to be realised. Nanotechnology also has the potential to contribute to many other technological areas, such as biosensing, catalysis and display technology, where the lead times may be much shorter.
