Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional electronic noses use correlation and pattern recognition techniques, then they can detect smells, but accuracy is poor and the range of detectable smells is limited
Solution Approach 1:
The patent replaces traditional classical computing mechanisms with quantum computing mechanisms. Quantum circuits with qubits perform olfaction analysis through quantum operations, substituting the mechanical correlation and pattern recognition processes with quantum superposition and entanglement-based computations, thereby achieving higher accuracy without proportional increases in complexity
Solution Approach 2:
The patent changes the fundamental parameters of computation from classical bits to quantum bits (qubits). This parameter change enables the system to represent and process smell data in a quantum state space, allowing for more efficient and accurate pattern recognition and molecular identification compared to traditional computational approaches
2Reliability
If traditional electronic noses detect smells, then they can identify current odor, but they cannot predict the future state of smells
Solution Approach 1:
The patent applies preliminary action by using quantum circuits to simulate and predict the future state of smells before actual detection occurs. The quantum model pre-computes potential odor trajectories and molecular transformations, allowing the system to anticipate future smell states rather than merely reacting to current detections, thereby improving reliability without significant time loss
3Adaptability or versatility
If quantum computing techniques are used to enhance detection range and accuracy, then performance improves significantly, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a quantum circuit architecture that can handle multiple detection tasks simultaneously. The same quantum hardware and algorithms detect current smells, predict future states, and identify molecular structures, making the system multi-functional. This universal approach increases detection range and versatility while managing complexity through shared computational resources

AI summary
In some implementations, an olfaction system may receive partition coefficients associated with one or more molecules detected in a headspace of a sample captured from an environment. The olfaction system may generate a quantum-ready dataset based on the partition coefficients using a partial quantum autoencoder that includes one or more quantum gate layers. The olfaction system may use a quantum approximate optimization algorithm to identify, within a spectrum of potential smells simulated by a quantum circuit, a set of smells emitted by the sample based on the quantum-ready dataset. The olfaction system may map a set of objects to the set of smells emitted by the sample. The olfaction system may predict a future state associated with the set of smells emitted by the sample using one or more hybrid quantum machine learning models.
