+   * **Quantum Money [Quantum Currency]()**
+     
+     - Wiesner's idea of "quantum money" suggests using quantum states to encode currency, making it practically impossible to forge due to the properties of quantum states.  
+     - The exact mathematical formulation varies depending on the implementation, but the general idea relies on quantum superposition and entanglement to ensure security and authenticity.
