Title:
QUANTUM COMPUTING DEVICE, QUANTUM COMPUTING SYSTEM, QUANTUM COMPUTING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/228312
Kind Code:
A1
Abstract:
This quantum computing device in a quantum computing system where a plurality of quantum computing devices connected to a network perform quantum secret calculations in cooperation with one another comprises: a sharing unit that applies double encoding to an input quantum state with a triply-even CSS quantum error correction code, and shares the encoded information obtained through encoding with other quantum computing devices; a verification unit that verifies whether the encoded information is correctly encoded; a computation unit that applies a quantum circuit to the encoded information; and a reconstruction unit that acquires an output quantum state that is the result of applying the quantum circuit to the input quantum state.
