Abstract: An improved scheme for sending classical digital data over a quantum channel is presented using path entanglement. The protocol is can detect digital data by the measurement or non-measurement of one entangled channel to signal to the remote station. The remote station is able to resolve the distant measurement by use of an interferometer. No measurement and the entangled state imply an interference effect at the remote station, whereas measurement results in a mixed state and no interference. A disproof of the “No-communication Theorem” is presented. The method applies to both matter and light waves.

Abstract: Methods for increasing the power output from a heat engine based on temporary electrical and magnetic remanence is achieved by a means of cancelling the power limitation caused by re-magnetization fields and methods for varying the turns-ratio of the output coils as the flux decays.

Abstract: This patent discloses methods for increasing the power output from earlier disclosures regarding a heat engine based on temporary electrical and magnetic remanence by R. O. Cornwall, for example WO00/0064038 entitled “Thermodynamic Cycles and Method for Generating Electricity” and filed Apr. 19, 2000. Presented is a means of cancelling the power limitation caused by re-magnetisation field and methods for varying the turns-ratio of the output coils as the flux decays.

Abstract: Exemplary embodiments of detection and transmission arrangements are disclosed herein. For example, some of the disclosed embodiments comprise a splitter, a detector, first and second paths defined between the splitter and the detector, and a manipulation arrangement. In certain embodiments, the splitter is arranged to direct an incoming particle along the first or second path depending upon the value of a parameter of the incoming particle. In particular embodiments, the manipulation arrangement is located on at least one of the first and second paths, so that, if a particle in a superposition of values of the parameter impinges on the splitter and a wavefunction of the particle is directed along both the first and second paths, the manipulation arrangement will act on the wavefunction to allow interference, at or near the detector, between the portions of the wavefunction that were directed along the first and second paths.

Abstract: One embodiment disclosed herein is an apparatus for performing a thermodynamic cycle comprising: a sample that exhibits temporary magnetic remanence; and a magnetisation apparatus for magnetising the sample, wherein the magnetisation apparatus is operable, during a first part of the thermodynamic cycle, to produce a cyclically-varying magnetising field comprising a wavetrain of a single or plurality of consecutive cycles, and to remove the magnetising field from the sample during a second part of the thermodynamic cycle, wherein demagnetisation of the sample during the second part of the thermodynamic cycle causes the generation of an independent magnetic flux.

Abstract: An apparatus for performing a thermodynamic cycle comprising: a sample having a ferromagnetic phase transition temperature; means to magnetise the sample above the ferromagnetic phase transition temperature of the sample; and means to cool the sample to a temperature that is below the ferromagnetic phase transition temperature thereof, wherein the demagnetisation of the sample whilst the sample is below the ferromagnetic phase transition temperature thereof causes the generation of an independent magnetic flux.
