Great attention has been paid to binomial codes utilizing bosonic systems as logical qubits with error-correction capabilities. However, implementing single-qubit rotation operations on Binomial codes has proven challenging, requiring an ancillary qubit in previous approaches. In the last talk, we proposed a method for performing logical qubit rotation on Binomial codes without requiring an auxiliary qubit. Specifically, we explained how to implement X-axis rotations by simultaneously applying two-frequency parametric drives to resonators with nonlinearity. Furthermore, we showed that Z-axis rotations could be realized with the detuning. Due to the reduction of the need for the ancillary qubit, the proposed approach seemed to be advantageous for quantum computation in the NISQ era, where the number of qubits is limited. Here, we study the performance of quantum error correction utilizing our proposed Binomial code, evaluated through numerical simulations. We calculate the fidelity of error correction performed on states subjected to the single-photon loss modeled by master equations. Despite the influence of decoherence during error correction, we observe an increase in fidelity compared to pre-correction states. These results demonstrate the utility of our proposal. |
