Document Type and Number:
Japanese Patent JP7061726
Kind Code:
B2
Abstract:
This application discloses a fault tolerant computation method and apparatus for a quantum Clifford circuit, a device, and a chip. The method includes: decomposing a quantum Clifford circuit into s logic Clifford circuits; preparing auxiliary quantum states corresponding to the s logic Clifford circuits; for each logic Clifford circuit, teleporting an input quantum state corresponding to the logic Clifford circuit to an auxiliary qubit, a quantum state obtained after the teleportation being processed by the logic Clifford circuit to obtain a corresponding output quantum state; measuring a corresponding error symptom based on the input quantum state and the auxiliary quantum state that correspond to the logic Clifford circuit during the teleportation; and performing error correction on the output quantum state corresponding to the logic Clifford circuit according to the error symptom, to obtain an error-corrected output quantum state. By using the technical solution of this application, fewer physical qubits and physical quantum gates are used while fault tolerant computation of a quantum Clifford circuit is efficiently implemented.
