1Productivity
If multiple quantum nonlinear oscillators are used for calculation, then computational capability is enhanced, but calculation accuracy deteriorates due to oscillator characteristic fluctuations
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the pumping signal parameters (amplitude and frequency) for each nonlinear oscillator based on its individual characteristics. The controller modifies these parameters to maintain optimal detuning conditions, thereby compensating for oscillator variations and improving calculation accuracy while preserving computational capability through multiple oscillators
Solution Approach 2:
The patent implements feedback control where the controller continuously monitors the state of each nonlinear oscillator and adjusts the pumping signals accordingly. This feedback mechanism ensures that detuning conditions are maintained despite oscillator characteristic fluctuations, resolving the contradiction between using multiple oscillators for computation and maintaining calculation accuracy
2Adaptability or versatility
If the number of connectors varies among oscillators, then adaptability to oscillator characteristics is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by providing each nonlinear oscillator with individually tailored pumping signal parameters rather than using uniform parameters for all oscillators. This localized adjustment of signal characteristics to match each oscillator's specific properties enables adaptability without requiring complex physical modifications to the device structure
Solution Approach 2:
The controller serves multiple functions by simultaneously managing varying numbers of connectors for different oscillators while also adjusting pumping signal parameters. This multi-functionality allows the system to adapt to oscillator characteristics through a single control unit rather than requiring separate control mechanisms for each oscillator, thereby managing device complexity
