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 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. analog, digital, or any combination thereof. | ||||||

| 87 | Neutrino communication arrangement | US764292 | 1977-01-31 | US4205268A | 1980-05-27 | Jozef W. Eerkens |
| A communication system comprising an emitter and a receiver (detector) utilizing modulated beams of neutrino and antineutrino waves as information carriers between the emitter and the receiver. Generation of modulated neutrino and antineutrino beams in the emitter is achieved by a maser-like medium, while detection and demodulation of the neutrino and antineutrino beams is accomplished by a second maser-like medium which registers the fluence (or flux) of modulated neutrinos and antineutrinos passing therethrough by means of resonant stimulated deexcitation of excited states. In addition to the information transmission utilization, the neutrino emitter and receiver (detector) system may also be employed to gather information by the probing of internal earth structures. Such structures cause measurable refractions and retardations of the propagated pulses of monochromatic coherent neutrino waves travelling through the earth between the emitter and receiver (detector), at certain predetermined neutrino frequencies. | ||||||
