Quantum cryptography by polarization ambiguity is generally used but it involves polarization-maintained fibers. This invention proposes an alternative: quantum cryptography by encoding on the phase of the interferogram of a particle flow. It comprises the conversion of a sequence of K bits of digital data into a train of K interferograms of particle flows of duration and frequency T, the state of the interferogram of the k<th >period depending on the value of the corresponding K bits. |
