Abstract

Quantum logic gates provide fundamental examples of conditional quantum\ndynamics. They could form the building blocks of general quantum information\nprocessing systems which have recently been shown to have many interesting\nnon--classical properties. We describe a simple quantum logic gate, the quantum\ncontrolled--NOT, and analyse some of its applications. We discuss two possible\nphysical realisations of the gate; one based on Ramsey atomic interferometry\nand the other on the selective driving of optical resonances of two subsystems\nundergoing a dipole--dipole interaction.\n
