In this study, we consider employing a virtual two-qubit gate (VTQG) as an error suppression technique. Here, we apply the VTQG to the digital quantum simulation of the transverse-field Ising model to suppress the errors. The obtained results indicate that the VTQG can be useful for suppressing quantum errors due to the additional SWAP gates. Additionally, by combining a pulse-efficient transpilation method with the VTQG, the further suppression of the errors is observed. |
