Researchers from countries such as the United States, Japan, Czech Republic and Poland have developed a prototype of a unique quantum of money. The key advantage of the new banknotes is that they can’t be copied, except with the permission of their owners.
According to scientists, themselves the money they have not yet received and currently they only have prototypes of banknotes. With the help of their developments in physics have the opportunity to show the wide possibilities that become available when the technology of the polarization of single photons.
It is noted that such a decision is likely to exclude the risk that will occur uncontrolled copy money without the permission of the owners of the notes. According to scientists, the simulation of quantum banknotes was carried out using quantum bits.
The idea that you can encode the serial numbers of banknotes belongs to Stephen Wiesner, he put it back in the 1970s. Quantum bits are different from conventional in that they handle different digital values, in addition to zeros and ones.
