Quantum Data Token Ensembles Using Projection Noise Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quantum data tokens are technologically demanding to create, control, and protect against unauthorized reading and copying, requiring high precision and complex systems.
Innovation Solution
A method is developed where qubits are combined into an ensemble, with the quantum state of a sub-ensemble having at most half the qubits being undeterminable due to quantum projection noise, ensuring unauthorized reading or copying is prevented by selecting an ensemble size that exceeds the technically necessary accuracy for reading, and authorized reading is achieved by aligning nuclear spins with a magnetic field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum key distribution is used to establish secure communication channels, then communication security is improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent creates a digital token that copies and represents quantum-secured communication credentials. Instead of requiring actual quantum hardware for every communication instance, a verified quantum security relationship is captured in a transferable token format, allowing multiple parties to benefit from the original quantum security establishment without each needing quantum equipment.
Solution Approach 2:
The quantum data token acts as an intermediary that mediates between quantum key distribution infrastructure and classical communication systems. The token contains encoded quantum security verification data that can be processed by classical systems, bridging the gap between quantum and classical domains without requiring direct quantum hardware integration at every level.
2Reliability
If quantum-secured communication channels are established for every transaction, then data protection is improved, but processing time and operational complexity increase
Solution Approach 1:
The system performs quantum security verification and key establishment in advance, before actual data transactions occur. The quantum data token is created and validated beforehand, containing pre-verified security credentials that can be quickly exchanged and validated during subsequent transactions without repeating the full quantum key distribution process each time.
Solution Approach 2:
The quantum security credentials are copied into a transferable token format that can be rapidly transmitted and verified. Instead of performing time-consuming quantum key distribution for every single data exchange, the pre-established quantum security is replicated in token form for efficient reuse across multiple transactions.
3Adaptability or versatility
If quantum data tokens are made transferable and storable, then utility and applicability are improved, but security risks and complexity of management increase
Solution Approach 1:
The patent extracts the essential quantum security verification data from the quantum key distribution process and places it into a self-contained, transferable token. This extracted token can be stored, transferred, and verified without requiring the original quantum hardware or continuous quantum channel access, enabling versatile usage while maintaining security through cryptographic binding to the original quantum verification.

AI summary
The invention relates to a method for generating a quantum data token on the basis of a system with a plurality of qubits. The invention is characterized in that a respective number (N) of qubits are combined in order to produce an ensemble and form an information unit, wherein each of the individual qubits of the ensemble is brought to precisely one specified identical quantum state, and the number (N) of qubits in an ensemble is selected such that the quantum state of a sub-ensemble, which has at most half of the qubits of the ensemble, cannot be determined due to quantum projection noise.
