Claim 3:
4. The method according to claim 2, wherein at least one of the following is provided:
each one of digit positions of the raw signal in the second data processing device corresponds to one of the plurality of quantum measurement parameters and to one of the plurality of quantum states;
the reconciled signal is determined in the second data processing device from the raw signal and the first encrypted signal by discarding one of the digit positions of the raw signal if a corresponding one of the plurality of quantum measurement parameters and a corresponding one of the quantum preparation parameters from the first encrypted signal do not match;
each one of first digit positions of the first raw signal in the first data processing device corresponds to one of the plurality of quantum preparation parameters and to one of the plurality of first quantum states; and
the first reconciled signal is determined in the first data processing device from the first raw signal and the encrypted signal by discarding one of the first digit positions of the first raw signal if a corresponding one of the plurality of quantum measurement parameters from the encrypted signal and a corresponding one of the quantum preparation parameters do not match.
