Quantum Currency States with No-Cloning Anti-Forgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional currency systems, both physical and digital, are susceptible to forgery and security threats from quantum computers, as they rely on cryptographic protocols that are not quantum-safe.
Innovation Solution
A quantum currency system is developed using a public and private key pair, where the public key includes a number n, a divisor m, and a subgroup H, and the private key includes a group G and an action ϕ, generating a quantum state that is stored in a physical system and verified using a Quantum Fourier Transform (QFT) to ensure authenticity, preventing counterfeiting by the no-cloning theorem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cryptographic protocols (e.g., RSA) are used for digital currency security, then current security requirements are met, but the system becomes vulnerable to quantum computer attacks
Solution Approach 1:
The patent changes the fundamental parameter of cryptographic security from classical computational hardness (RSA) to quantum mechanical properties (no-cloning theorem, quantum entanglement). This involves transitioning from bit-based cryptographic protocols to quantum state-based currency representation, where the security parameter becomes the quantum state's不可复制性 rather than mathematical problem difficulty.
Solution Approach 2:
The patent replaces the mechanical/computational cryptographic system with a quantum physical system. Instead of relying on computational complexity to prevent forgery, the system uses quantum mechanical principles (no-cloning theorem, measurement collapse) to provide inherent security, substituting classical information theory with quantum information theory.
2Reliability
If physical currency security features (e.g., watermarks, serial numbers) are added, then forgery complexity increases, but verification time becomes impractical for short transactions
Solution Approach 1:
The patent replaces complex physical security features with quantum state verification. Instead of manually or computationally checking multiple physical security characteristics (watermarks, serial numbers, holograms), the system uses quantum measurement to verify currency authenticity in a single operation, leveraging the quantum no-cloning theorem to provide instant verification without time-consuming checks.
Solution Approach 2:
The patent changes the verification parameter from multiple physical feature checks to a single quantum state measurement. The currency's quantum state encodes all security information, allowing verification to be performed by measuring quantum properties rather than checking multiple separate physical characteristics, thereby reducing verification time.
3Productivity
If digital currency information is stored and transferred, then transaction efficiency improves, but the system becomes susceptible to information cloning and secret theft
Solution Approach 1:
The patent replaces digital information storage and transfer with quantum state storage and transfer. Instead of storing currency information as classical data that can be copied, the system stores it as quantum states that cannot be cloned. Transaction efficiency is maintained through quantum state transfer protocols while security is enhanced by the fundamental quantum property that prevents information cloning.
Solution Approach 2:
The patent changes the information representation parameter from classical bits to quantum states. This fundamental parameter change enables both efficient transaction processing (through quantum parallelism and superposition) and enhanced security (through the no-cloning theorem), resolving the contradiction between productivity and reliability.
