Counterfeit or counterfeit money is a big problem around the world. Many people face trouble with counterfeit or fake money. To solve this problem, scientists are working to launch quantum currency in the style of science fiction. A new study has shown that a small amount of quantum information can work like a debit card. As a result, this currency can be used without leaving any opportunity for counterfeiting, forgery or fraud.

According to scientists, quantum currency does not depend on paper notes or digital codes. Quantum currency stores information in a quantum state. Quantum currency basically stores information in the spin of an electron or the polarization or polarization state of a photon. The basic idea of ​​quantum currency was proposed by Stephen Wiesner in 1983 as conjugate coding. Since quantum states cannot be copied perfectly, quantum currency can be easily detected if an attempt is made to clone it.

The effectiveness of the quantum currency system has been tested under the leadership of scientist Julien Lorat at the Kastler Brossel Laboratory of the Sorbonne University and CNRS in Paris, France. During this time, scientists sent a single photon in a very weak light pulse, which carries a bit-like quantum state called a qubit. This state exists as a polarization of light. These states are loaded into a quantum memory.

According to the research results published in the journal Science Advances, scientists have given special importance to the idea of ​​no-cloning in this study on quantum currency. This is a concept in quantum physics where it is believed that there is no possibility of creating a perfect copy of an unknown quantum state. Scientists have linked this rule to financial transactions and secure storage systems.
