Abstract

The aim of this project is to develop new practical schemes for high precision measurement in optics and electronics, using quantum entanglement and error correction. Entanglement enables a more efficient use of physical resources than classical physics, and increases the precision of measurements. The strategies proposed are to reduce the effects of the noise due the interaction of quantum systems with the surrounding environment. The proposed schemes are ali based on current laboratory technologies (cavity QED, ion-traps, and mesoscopic electronics) and reasonable extrapolations of those technologies. (AU)
