*'' Interaction and Client’s Computation'': Server prepares a Bell pair and sends one half of the Bell Pair to the Client. The Client informs the Server if she receives it or else if she doesn’t, Client asks Server to send it again. The client measures her share of entangled pair in a certain measurement basis depending on her MBQC pattern. The Server then entangles his share of Bell pair and qubit of the resource state using CZ gate which transfers the gate/ measurement operated by Client to the resource qubit. Then he measures the resource qubit in X basis and communicates his classical measurement outcome to the Client. Client records it and uses it to compute her final outcome. | *'' Interaction and Client’s Computation'': Server prepares a Bell pair and sends one half of the Bell Pair to the Client.
