Measurement outcomes of qubits is not certain, hence it renders MBQC a non-deterministic model. This can still be rectified by invoking Pauli corrections based on the previous outcomes, as evident from above. For example, to implement Hadamard gate on input state <math>|\psi_i\rangle = a|0_i\rangle + b|1_i\rangle</math>, we consider the case of a two qubit graph state <math>C_{ | Measurement outcomes of qubits is not certain, hence it renders MBQC a non-deterministic model.
