Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum-equipped devices use quantum computing to break encryption, then security of data transmission is improved, but existing non-quantum encryption schemes become vulnerable
Solution Approach 1:
A quantum network gateway is introduced as an intermediary component between non-quantum-equipped devices and quantum-equipped devices. The gateway receives communication requests from non-quantum devices, generates quantum tokens, and facilitates authentication using quantum security protocols, thereby protecting non-quantum devices from quantum-based attacks without requiring them to have quantum capabilities.
Solution Approach 2:
The system transitions from classical encryption parameters to quantum-based security parameters. Quantum tokens are generated using quantum key distribution protocols, and authentication mechanisms are changed from traditional cryptographic verification to quantum-verified authentication, fundamentally changing the security parameter space from classical to quantum domain.
2Reliability
If quantum network gateway is introduced to facilitate secure communications, then security and functionality are improved, but device complexity increases
Solution Approach 1:
The quantum network gateway is designed with multi-functional capabilities: it serves as an authentication server for non-quantum devices, acts as a quantum token generator, functions as a protocol translator between classical and quantum communication protocols, and provides secure channel establishment. This consolidation of multiple functions into a single gateway reduces overall system complexity compared to having separate specialized components for each function.
3Reliability
If quantum tokens are generated for authentication, then authentication security is improved, but processing time and computational overhead increase
Solution Approach 1:
Quantum keys and tokens are generated and distributed in advance before actual communication occurs. The quantum network gateway pre-establishes quantum-secured authentication credentials with authorized devices, so that when communication is needed, the authentication process can proceed more quickly by verifying pre-generated tokens rather than performing full quantum key distribution during the communication event.

AI summary
A quantum communication system for enabling secured communications between non-quantum equipped and quantum equipped devices comprises a non-quantum equipped network device configured to transmit a connection request, a quantum authentication server configured to verify a connection between the non-quantum equipped network device and a quantum network gateway, the quantum network gateway enabling communications between the non-quantum equipped network device and the quantum authentication server. The quantum network gateway includes at least one quantum processor, and a quantum application, which when executed by the quantum processor, cause the quantum application to receive, from the non-quantum equipped network device, a request to communicate with an application server, generate a quantum token, transmit the quantum token to the quantum authentication server for authentication of the communication request, and set up, a communication tunnel between the quantum network gateway and the application server for communicating on behalf of the non-quantum equipped network device.
