Engineering Contradiction Analysis
1Productivity
If quantum computers are used to solve complex computational problems, then solution accuracy and processing speed are improved, but hardware complexity and operational difficulty worsen
Solution Approach 1:
The patent introduces a hybrid quantum-classical computing system where a classical computer acts as an intermediary between the problem formulation and the quantum computer. The classical computer prepares the computational problem, encodes it into quantum operations, and processes the results, thereby shielding users from direct quantum hardware complexity while maintaining quantum processing advantages
Solution Approach 2:
The computational task is segmented into distinct phases: classical problem preparation and encoding, quantum state manipulation and computation, and result measurement and interpretation. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining high processing speed
2Measurement precision
If quantum computers are used to solve complex computational problems, then solution accuracy is improved, but operational complexity worsens
Solution Approach 1:
The system implements automated algorithms that perform problem encoding, quantum circuit generation, and result analysis without requiring manual quantum operations. The hybrid system self-manages the complex quantum-classical interface, allowing users to operate the system through standard classical computing interfaces while maintaining high solution accuracy
Solution Approach 2:
The system incorporates iterative feedback loops where measurement results from the quantum computer are fed back to the classical processor, which then adjusts the problem encoding or quantum circuit parameters to improve solution accuracy. This automated feedback mechanism simplifies operation while enhancing precision
3Ease of operation
If classical computers are used for molecular simulations, then ease of operation is maintained, but computational cost and time increase
Solution Approach 1:
The patent applies quantum computing resources selectively to the most computationally intensive portions of molecular simulations, such as electron correlation calculations, while using classical computers for less demanding tasks like molecular geometry optimization. This partial application of quantum computing maintains ease of operation for overall workflow while significantly reducing computational time for critical subtasks

AI summary
A method for encoding quantum information comprising at least one Kronecker product of Pauli X, Y, Z matrices, an identity matrix e and a phase term comprises providing binary indices for each term and using them in a binary representation of the Kronecker product, including first and second arrays corresponding to respective digits of a two-digit binary code. The encoding method provides computational and storage advantages. A set of ILC entanglers can be generated using the encoding method. Entanglers encoded in a binary representation can be conveniently prioritized and selected for a provided Hamiltonian, including in a multiple loop iterative fashion, to provide a set of quantum logic gates in a quantum circuit of a quantum computer.
