Application: Classical computer, information processing method, and computer readable medium (Patent ID: US20240080185A1)

The patent filed by Nippon Telegraph and Telephone Corp. describes a classical computer that computes probabilities related to the preparation and measurement of quantum states by a quantum computer. The computer uses measurement results to calculate state space probability, Pauli measurement probability, and magic state probability to determine the accuracy of quantum state preparation and measurements. The classical computer generates public and trapdoor keys, performs Z and X basis checks, and computes a degree of approximation between quantum states and magic states of CCZ.

Furthermore, the classical computer executes multiple quantum state generation and measurement sequences, computes probabilities based on measurement results, and uses random numbers for computation selection and measurement validation. The method involves generating public and trapdoor keys, performing Z and X basis checks, and determining the accuracy of generalized stabilizer measurements. Additionally, the patent covers an information processing method and a computer-readable medium storing a program for classical computers to execute processes related to state space probability, Pauli measurement probability, magic state probability, and approximation accuracy computation for quantum states and measurements.
