*'''Squeezing.''' Client instructs Server to measure all the qubits of the control register in some basis chosen randomly by the Client, except the last one, and return to her the outcomes. The last unmeasured state contains the randomly prepared qubit hidden from the Server. Client can then compute the value of r by an equation (see Pseudo Code). This equation depends only on Client’s measurement basis angles, Server’s measurement outcome and the location of random X’s (unknown to the Server). Thus, the Client knows the state of her secret qubit prepared by the Server. | *'''Squeezing.'''
