Solution Overview
Problem
Current quantum SWAP gate protocols are vulnerable to eavesdropping and tampering, as they lack mechanisms for authentication and error correction, which can lead to inaccurate qubit state swaps and compromise the confidentiality and integrity of quantum information.
Innovation Solution
Implementing secure quantum SWAP protocols using secret quantum gate ciphers that anti-commute with the computational basis of two-qubit gates across specific axes of the Bloch sphere, along with commutation correction operations to ensure accurate qubit state swaps, thereby preventing eavesdropping and tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard quantum SWAP gate protocols are used, then the quantum swap operation can be performed, but the system is vulnerable to eavesdropping and tampering without authentication and error correction mechanisms
Solution Approach 1:
The patent applies preliminary action by establishing authentication mechanisms and error correction protocols before the quantum swap operation begins. The parties exchange authentication information and set up correction procedures in advance, so that when the swap occurs, the security and reliability are already in place without adding complexity during the actual swap operation.
Solution Approach 2:
The patent introduces intermediary elements in the form of authentication protocols and error correction codes that mediate between the two parties performing the swap. These intermediaries provide the necessary security verification and error handling without requiring the parties to directly trust each other, thus improving reliability while maintaining manageable complexity.
2Reliability
If quantum gate ciphers are applied to protect quantum information, then confidentiality is improved, but the computational overhead increases
Solution Approach 1:
The patent applies parameter changes by selecting specific quantum gate operations with particular properties that provide security while minimizing computational overhead. By carefully choosing the parameters of the quantum gates used as ciphers, the system achieves confidentiality without excessive computational cost.
Solution Approach 2:
The patent uses disposable quantum gate ciphers that are applied once and then discarded or replaced. These single-use cryptographic operations provide strong confidentiality protection for each swap operation without requiring long-term computational resources, thus maintaining efficiency while improving security.
3Manufacturing precision
If commutation correction operations are performed to ensure accurate qubit state swaps, then manufacturing precision is improved, but the number of operations increases
Solution Approach 1:
The patent applies feedback by using commutation correction operations that respond to the specific state of the quantum system. The correction operations are determined based on the actual commutation relationships observed during the swap, allowing for precise correction with minimal additional operations rather than applying fixed overhead corrections.
