The present disclosure relates to a method for mitigating an error of a quantum circuit in a quantum computer, the method including: detecting a quantum circuit to be mitigated among a plurality of quantum circuits forming the quantum computer; invoking a pre-trained deep learning model for mitigating an error of the plurality of quantum circuits; inferring an error correction value of the detected quantum circuit using the invoked deep learning model; and mitigating an error of the detected quantum circuit based on the inferred error correction value.

Method for mitigating error of quantum circuit and apparatus thereof

The present disclosure relates to a method of mitigating errors in quantum circuits constituting a quantum computer, which includes: obtaining a plurality of pieces of first probability matrix information according to a sequence of quantum gates constituting a quantum circuit; obtaining a plurality of pieces of second probability matrix information according to a sequence of quantum gates constituting the quantum circuit; generating a plurality of pieces of differential matrix information based on the plurality of pieces of first and second probability matrix information; and generating error mitigation matrix information corresponding to the quantum circuit using the plurality of pieces of differential matrix information.

Method for mitigating an error of quantum circuit and apparatus thereof

The present invention relates to the architecture of a quantum RAM, a method for using classical data in quantum computing by inputting the classical data as quantum data, and a system and method of operating a quantum database using the architecture. Quantum computing can achieve an exponential speed-up in some applications using a large parallel process provided by a quantum database in which information can be superposed. The present invention proposes an efficient quantum database architecture and protocol that can record and search for classical information with a quantum circuit.
