* '''Input qubits:''' For the input qubit states, each client one-time pads their qubit and uses secret sharing schemes to share the secret values with other clients. The honest behaviour for every client is enforced via the given protocol. The server then one-time pads them and measures the one-time padded qubits and announces the measurement values. | * '''Input qubits:''' For the input qubit states, each client one-time pads their qubit and uses secret sharing schemes to share the secret values with other clients.
