Abstract: The invention relates to a method and device which are intended for remote control and communication using nuclear isomers. Several samples of nuclides that can have a metastable state are irradiated together and simultaneously with cascade gamma-rays emitted from a radioactive source or a particle accelerator. According to quantum mechanics, the gamma-rays produced are entangled, and said entanglement is transferred to the nuclear isomers. When the samples are separated and one of said samples, namely the master, is stimulated using a standard gamma- or X-ray irradiation method, the other samples, namely the slaves, are also deexcited. There is no known method for interference between the masters and slaves. Only the slave(s) can receive the signal instantly from the master through any medium and over any distance. The method and device are particularly suitable for communication and control applications.

Abstract: The invention relates to a method and device for modifying the probability of deexcitation in relation to isomer nuclides, consisting in exciting samples containing nuclides having a metastable state with a half-life varying between one microsecond and 50 years. The excitation is achieved by irradiation with entangled gamma rays produced either by a radioactive isotope, which emits a gamma-ray cascade, or by collisions between accelerated particles and a target, caused by the Bremsstrahlung effect. According to Quantum Mechanics, the gamma-rays produced are entangled, and said entanglement is transferred to the nuclei of the isomer nuclides. As a result, each isomer of the radioactive product obtained has a half-life, which can vary over time and which is initially lower than the theoretical half-life thereof.
