Typically, communication between devices is created using electromagnetic radiation: this principle works
The authors of the new work have created their own method of transmitting information, with which you can bypass the disadvantages of electromagnetic communication.
They transmitted digitally coded informationusing neutrons. To do this, scientists measured what the spontaneous emission of fast neutrons will be during the decay of californium-252 - this is a radioactive isotope that is formed in nuclear reactors. To track the reactions, the authors recorded the information using a detector and analyzed the data obtained through software on a regular laptop.
Next, the researchers encrypted different sets of information, such as one word, a letter and a number. To do this, they converted the information into neutron field modulation, and decoded the result on a laptop.
A double-blind test was performed, during whichthe number obtained with the random number generator was coded in such a way that scientists did not know its meaning. The number was then transmitted via a "neutron link" to a laptop and decoded. All communication tests were 100% successful.
The researchers note that their system can beused to protect and transmit information about the operation of nuclear reactors, as well as for shipping routes, since it does not require a large number of cables and works even in places where the penetration of electromagnetic waves is difficult.
