Engineering Contradiction Analysis
1Adaptability or versatility
If classical digital circuitry is used to simulate quantum algorithms, then quantum computing can be implemented on existing devices, but the number of electronic components increases exponentially and multi-particle entanglement cannot be achieved
Solution Approach 1:
The patent uses classical electronic signals to copy and represent quantum states. Each qubit is represented by two classical signals (I and Q components) that together encode the quantum state information, allowing quantum algorithms to be simulated without requiring actual quantum hardware
Solution Approach 2:
The patent segments the representation of quantum entanglement into manageable classical signal processing operations. By dividing the quantum state into I and Q signal components, the system can process entangled states using separate classical signal paths that combine to reproduce quantum behavior
2Adaptability or versatility
If classical digital circuitry is used to simulate quantum algorithms, then existing devices can be utilized, but the execution time increases exponentially
Solution Approach 1:
The patent employs periodic clock signals to drive the simulation of quantum operations. By using synchronized periodic signals for the I and Q components, the system can process multiple quantum operations in a time-multiplexed manner, reducing overall execution time compared to sequential processing
Solution Approach 2:
The patent replaces quantum mechanical operations with classical signal processing operations. Quantum gate operations are simulated using classical digital logic gates that manipulate voltage signals, substituting quantum physics with electronics to achieve faster processing on classical hardware
3Productivity
If quantum computing methods are used, then quantum algorithms can be executed natively, but the device complexity and resource requirements are extremely high
Solution Approach 1:
The patent creates a universal simulation platform that can execute any quantum algorithm using standard classical digital logic components. The same I-Q signal representation and logic gate framework can simulate different quantum gates (Hadamard, CNOT, Phase shift) and algorithms, providing multi-functionality without requiring specialized quantum hardware for each operation
