Quantum money that uses the mathematics of knots could be unforgeable

A financial system constructed utilizing a mixture of quantum computer systems and the arithmetic of knots might be unattainable to counterfeit

Quantum cash underpinned by the arithmetic of knots might be unattainable to forge.

In a quantum financial system, cash is represented as a set of quantum bits – qubits – on a quantum pc. There is a secret process for creating the cash that solely the authority in cost, equivalent to a mint, can carry out. And copying the quantum cash is unattainable due to a legislation of physics referred to as the no-cloning theorem. Effectively, if somebody realized sufficient details about the quantum cash to duplicate …
