1Reliability
If Flip-Flop QRAM architecture is used to record superposed data, then quantum RAM can store classical data in quantum superposition state, but device complexity increases to O(N log N)
Solution Approach 1:
The patent extracts and eliminates redundant components from the Flip-Flop QRAM architecture. By removing unnecessary quantum gates and simplifying the circuit structure, the device complexity is reduced from O(N log N) to O(log N) while preserving the core functionality of storing classical data in quantum superposition state.
Solution Approach 2:
The patent inverts the traditional approach by using a simplified quantum circuit architecture that achieves the same storage capability with fewer resources. Instead of using complex Flip-Flop mechanisms, the invention employs an inverted design that directly maps classical data to quantum superposition states through optimized quantum gates, reducing overall device complexity.
2Productivity
If large classical data is recorded and provided to quantum computer in quantum superposition, then computing speed is exponentially improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical quantum circuit structures with a streamlined architecture that uses optimized quantum gates. By substituting the traditional Flip-Flop mechanical structure with a simplified gate-based system, the invention achieves exponential computing speed improvement while reducing device complexity to O(log N).
Solution Approach 2:
The patent changes key parameters of the quantum RAM architecture, specifically optimizing the number of quantum gates and circuit depth. By adjusting these parameters to achieve O(log N) complexity, the system maintains exponential computing speed improvement while reducing the resource requirements and device complexity.
