- Abstract: To mitigate the noise in quantum channels, calibration is used to tune the
devices to minimize error. Generally, calibration is performed by transmitting
pre-agreed-upon calibration states and determining an error cost so the two
parties can tune their devices accordingly. The calibration states can be the
same ones used for the desired protocol, and so an untrusted party could
potentially learn which protocol is being performed by gathering knowledge of
the calibration states and cost function. Here, we assume privacy of the
protocol is the goal and therefore the receiver should not be allowed to
determine the protocol states. We limit the information that is revealed to the
receiver, and in this regard, we propose a simple protocol that hides the
calibration states and cost function from the receiver, but still allows for
calibration to be performed efficiently, thereby increasing the privacy of the
protocol. We show various numerical results demonstrating the ability of the
protocol under various channel noise parameters and communication scenarios.
