1Reliability
If classical protocols are used for verifying data integrity, then verification can be performed, but communication complexity is high requiring transmission of large number of bits
Solution Approach 1:
The patent replaces classical mechanical information processing with quantum mechanical operations. Quantum gate operations act on quantum states representing data fingerprints, enabling verification with exponentially fewer qubits transmitted compared to classical bit transmission. The quantum system uses superposition and entanglement to process verification information more efficiently.
Solution Approach 2:
The patent changes the fundamental parameter of information representation from classical bits to quantum qubits. This parameter change enables the system to exploit quantum properties such as superposition and entanglement, achieving exponential reduction in communication complexity while maintaining verification reliability.
2Reliability
If classical protocols are used for data verification, then verification is possible, but incremental updates cannot be performed in constant time
Solution Approach 1:
The patent prepares quantum states representing data fingerprints in advance using quantum circuit operations. These pre-prepared quantum states can be quickly updated by applying additional quantum gates when data changes occur, enabling constant-time incremental updates without reprocessing the entire dataset.
Solution Approach 2:
The patent creates a dynamic quantum verification system where quantum states can be efficiently updated through quantum gate operations. The system transitions from static verification to dynamic updates, allowing incremental changes to be processed in constant time by applying针对性的 quantum operations to the existing quantum states.
3Quantity of substance
If quantum comparing protocols are used, then communication complexity is reduced exponentially, but quantum gate operations are required
Solution Approach 1:
The patent develops universal quantum circuits that can process different types of data verification tasks using the same quantum gate operations. The quantum verification system is designed to be multi-functional, handling various verification scenarios with a standardized set of quantum operations, reducing the overall complexity burden.
Solution Approach 2:
The patent uses quantum state copying and replication techniques where standardized quantum circuit patterns are reused across different verification instances. By copying and adapting proven quantum circuit designs, the system reduces the complexity of implementing quantum gate operations from scratch for each verification task.
