Quantum money that uses the mathematics of knots could be unforgeable

A monetary system built using a combination of quantum computers and knot mathematics may be impossible to counterfeit

Quantum money backed by the mathematics of knots may be impossible to counterfeit.

In the quantum monetary system, money is represented as a collection of quantum bits (qubits) on a quantum computer. There are secret procedures for creating money that can only be performed by personnel such as the Mint. And thanks to a physical law called the no duplication theorem, it is impossible to copy quantum money. In effect, if someone learns enough information about quantum money to replicate…
