It is shown that the masking process will be implemented successfully if the targeted masked qubit evolves by Hermitian or non-Hermitian energy operators. For a two-qubit system, we showed that a single ancillary (blank). A single qubit is sufficient to mask the encoded information in this two-qubit system. Similarly, the process can be performed if the initial qubits system evolves by Hermitian or non-Hermitian energy operator.
