Abstract: An array of discrete, microscopic particles in a substantially fixed spatial relationship with respect to each other is constructed by using an STM to position CO molecules on the (111) surface of a copper crystal. The particles of the array are arranged so that the array performs a logic operation (such as AND and OR) when input to the array is provided. This input takes the form of moving one or more of the particles, thereby triggering a cascade of motion through the array, which leads to output from the array. More generally, the array may be used to propagate motion by sequentially inducing movement of particles in the array.

Abstract: A system and method for transferring information between spatially distinct points by modulating quantum states operatively coupling at least one transmitter and at least one receiver. In the preferred embodiment, fabrication of an elliptical quantum corral resonator on a length scale on the order of the electron wavelength enables the engineering of substantially confined quantum states as desired. A transmitter preferably located at a wavefunction antinode affects a modulation in the quantum states, and a receiver preferably located at a different wavefunction antinode detects the affected modulation in the spatially distributed quantum states. A second exemplary embodiment exploits the orthogonality of quantum wavefunctions to enable multiple channels of information to be transferred simultaneously through the same volume of space without crosstalk. Additional embodiments enable combinational processing of transferred information, which may be in any format, e.g.
