Application: Molecular structure optimization system, molecular structure optimization method, and parameterized quantum circuit (Patent ID: US20240096452A1)

The patent filed by Toshiba Corp describes a molecular structure optimization system that utilizes both a quantum computer and a classical computer. The quantum computer employs a parameterized quantum circuit to calculate a loss function based on a coordinate parameter of a target molecule, while the classical computer updates the coordinate and circuit parameters to determine optimal values. The system involves a variational optimization procedure that iterates until a stop condition is met, with the classical computer utilizing a Bayesian optimization algorithm to update the parameters effectively.

The claims associated with the patent outline the components and steps involved in the molecular structure optimization system and method. These include the use of a quantum computing step to calculate the loss function, an update step to adjust the parameters based on the loss function, and an optimization step that repeats the process until optimal values are determined. The system is designed to handle different molecular structures, such as ground-state or transition-state, by minimizing or maximizing the loss function accordingly. Additionally, the patent covers the use of a parameterized quantum circuit with optimized circuit parameters for efficient molecular structure optimization.
