Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum computing systems are used to achieve entanglement, then quantum nonlocality and probability amplitude superposition are obtained, but scalability is limited, low temperature operation is required, and computation time is short
Solution Approach 1:
The patent replaces quantum mechanical systems with classical acoustic wave systems. Classical acoustic waves can exhibit entanglement-like behavior (inseparability) without requiring quantum conditions such as low temperature operation. This substitution allows the system to achieve reliable entanglement stability while improving scalability, as classical acoustic systems can operate at room temperature and are easier to scale up in size and complexity.
2Device complexity
If classical wave systems are used to achieve classical entanglement, then scalability and room temperature operation are improved, but the dimension of the product Hilbert space is limited by the number of available degrees of freedom
Solution Approach 1:
The patent introduces nonlinear acoustic waves to access additional dimensions in the Hilbert space. While linear classical systems are limited by the number of degrees of freedom, nonlinear waves can span Hilbert spaces with exponentially scaling dimension. This is achieved by utilizing the nonlinear interaction of acoustic waves, which creates new state spaces that grow exponentially with the number of waves, thereby dramatically increasing the effective Hilbert space dimension without adding more physical degrees of freedom.
3Quantity of substance
If nonlinear acoustic waveguides are used to create phi-bits, then Hilbert space dimension with exponential scaling is achieved, but system complexity increases
Solution Approach 1:
The patent segments the complex nonlinear acoustic system into multiple independent or weakly coupled waveguides, each supporting nonlinear acoustic waves. By dividing the system into manageable segments (individual waveguides), the overall complexity is reduced while still achieving exponential Hilbert space scaling. Each waveguide can be controlled and characterized separately, making the system more tractable despite the nonlinear effects.
Solution Approach 2:
The patent employs acoustic waveguides that can serve multiple functions: they guide acoustic waves, support nonlinear interactions, and enable the creation of phi-bit states. This multi-functionality reduces the need for additional specialized components, thereby managing system complexity while achieving high-dimensional Hilbert space utilization through nonlinear acoustic effects.
