Engineering Contradiction Analysis
1Ease of manufacture
If universal encoding is used to prepare chemistry problems, then the encoding process is simple and universal, but qubit consumption is not optimized and resource efficiency is poor
Solution Approach 1:
The patent changes the encoding parameters by introducing chemistry-inspired orbital ordering and hamming weight constraints to transform the universal encoding into a chemistry-optimized encoding scheme that reduces qubit consumption while maintaining encoding capability
Solution Approach 2:
The patent applies local quality by tailoring the encoding strategy to specific chemistry problem characteristics, using orbital ordering and hamming weight preservation to optimize qubit usage for molecular electronic structure problems rather than using a one-size-fits-all universal encoding
2Ease of manufacture
If hardware-friendly circuit design approaches are used, then circuit implementation is simplified, but chemistry problem solving accuracy is insufficient
Solution Approach 1:
The patent merges hardware-friendly circuit design principles with chemistry-inspired algorithms by combining orbital ordering, hamming weight preservation, and circuit design optimization to achieve both implementation simplicity and solving accuracy for chemistry problems
3Measurement precision
If chemistry-inspired algorithms are used, then chemistry problem accuracy is improved, but quantum logic gate burden increases
Solution Approach 1:
The patent extracts and utilizes only the essential chemistry information needed for accurate problem solving, focusing on orbital ordering and hamming weight constraints while filtering out redundant chemistry details that would increase circuit complexity and gate burden
4Adaptability or versatility
If current chemistry universal encoding and circuit design are used separately, then each component can be optimized independently, but synergy is lost and solving efficiency is reduced
Solution Approach 1:
The patent creates a unified encoding and circuit design framework that serves multiple functions: it provides chemistry-accurate problem representation, optimizes qubit consumption, reduces circuit complexity, and enables efficient solving while maintaining flexibility for different chemistry problems

AI summary
Provided are a quantum encoding method and a system to express the electron orbital distribution of electrons in complex molecules as a first Hamiltonian in a binary manner, and to compress the first Hamiltonian into a second Hamiltonian. Not only can it reduce the demand for qubits in circuit design, but it can also be combined with the chemical substrate arrangement to connect the hamming weight of the compressed state with the electronic transition information, so that the chemical experience in searching for low-energy states may be applied to circuit design, and ultimately matched Fixed hamming weights were proposed to complete the final design.
