Engineering Contradiction Analysis
1Quantity of substance
If quantum data is stored and processed in quantum devices with large Hilbert space dimensions, then the capacity to handle quantum data is improved, but the complexity of the system increases
Solution Approach 1:
The system divides quantum data processing into separate functional modules: quantum random access memory (QRAM) for storage, quantum computers for computation, and quantum communication networks for data transfer. This segmentation allows each component to be optimized independently while working together to handle large quantum datasets without requiring a single monolithic complex system
Solution Approach 2:
The patent introduces quantum communication networks as intermediaries between quantum devices and classical systems, enabling efficient data transfer and interaction. This intermediary layer simplifies the overall system architecture by providing standardized interfaces and protocols for quantum data handling, reducing the complexity of direct integration between components
2Speed
If quantum computation is performed locally, then computation speed is improved, but communication costs and resource requirements increase
Solution Approach 1:
The patent combines quantum random access memory with quantum computers to create an integrated quantum data center architecture. This merging allows quantum data to be stored and processed within the same quantum system, eliminating the need for frequent data transfer between separate devices and reducing communication overhead while maintaining high computation speed
Solution Approach 2:
The quantum data center architecture provides multi-functional capabilities through a single integrated system that can perform storage, computation, and communication functions. This universal platform reduces the need for multiple specialized devices and minimizes the total communication costs by consolidating operations within one system
3Productivity
If quantum data is processed without encryption, then processing efficiency is improved, but data security and privacy are compromised
Solution Approach 1:
The patent applies quantum key distribution and quantum encryption protocols that leverage quantum mechanical properties (such as superposition and entanglement) to create secure data transmission channels. These quantum-based encryption methods maintain processing efficiency while ensuring data security, as the encryption keys are generated and managed through quantum operations rather than classical computational methods

AI summary
A quantum data center includes a quantum computer and a transceiver. The transceiver is in communication with the quantum computer and is operable to communicate with a remote user via a quantum communication network. The quantum computer (i) receives, via the transceiver, a quantum input state from the remote user, (ii) stores, in a quantum random access memory, a plurality of database states in a plurality of database qudits forming a database register, (iii) queries the quantum random access memory with the quantum input state to retrieve, from the database register, a quantum output state that is based on one or more of the plurality of database states, the quantum output state being disentangled from the quantum input state and the plurality of database states, and (iv) transmits, via the transceiver, the quantum output state to the remote user.
