The Client uses skL, which was not used to create any gadget (Gadgets used 0-(L-1) secret keys only) and decrypts sent encryptions to obtain the pad key. The pad key thus obtained determines the Pauli operations on the sent quantum state to obtain the final and correct outcome of the computation. The client performs the required operations on individual qubits of the quantum state and gets the output of his computation. | The Client uses skL, which was not used to create any gadget (Gadgets used 0-(L-1) secret keys only) and decrypts sent encryptions to obtain the pad key.
