MicroAlgo’s new approach addresses the challenge of designing optimal exact quantum query algorithms for Boolean functions. By leveraging the sum-of-squares representation of multilinear polynomials, the framework reveals internal function structure and establishes a mathematical basis for improved query complexity.

Step One extracts sum-of-squares decompositions of the Boolean function and its negation via algebraic methods. Step Two constructs the assumed final quantum state through qubit initialization, phase modulation and gate operations. Step Three optimizes unitary operators using mathematical optimization and machine learning to maximize query efficiency.

Though initially focused on low-complexity Boolean functions, the framework promises broader impact across quantum communication, security and machine learning. Scalability to complex functions, potential integration into large-scale quantum data processing and challenges in real-world feasibility will guide further development.
