the transmission is secure as one can detect whether the transmitted data has been listened to.
- using entangled photon communication, the exact polarisation of photons having transmitted data is compared at both ends of the line.
- data communication for that process can be done in clear but certified by a our quantum safe signature
- the photon emitter, the transmission line between the photon emitter, and the data receiver are placed in the same box so they cannot have their properties modified, if optical fibres are used for the photon transmission.
any photon sent to and received by the data emitter, entangled to a third party , will take the place of a proper entangled photon and the count of properly encoded photons at the data receiver will not be met : the data will not be transmitted.
This is because the properties of the fibre or of the photon transmission could otherwise be modified by using a different fibre or transmission mean, for instance with better transmission properties , preventing the receiver from noticing a decrease in the count of properly encoded photons when the line is being listened to.
