Abstract: A quantum communication system including an emitter of entangled photons, including a source configured in order to generate at least one pair of entangled photons. The at least one pair of entangled photons including a first photon (P1) emitted on a first propagation path (D1) and simultaneously a second photon (P2) emitted on a second propagation path (D2) different to the first propagation path. A first receiver arranged on the first propagation path (D1), including a complex absorber to absorb the photon in a polarization state selected from among the states of at least two different pairs of complementary polarization states. A second receiver arranged on the second propagation path (D2), including an optical amplifier making it possible to multiply the second photon (P2) while preserving its polarization and a measuring instrument making it possible to measure the average polarization of the multiplied photons.

Abstract: An optical communication system includes a polarized-light emitter having a source (1) configured to generate at least one photon polarized with a determined polarization on a propagation path; and a complex polarization modifier (2) placed on the propagation path of the light generated by the emitter, configured to modify the polarization direction of the light and introduce a phase shift between two perpendicular components of the electric field of the light. A receiver (3) is arranged on the propagation path of the light, downstream of the complex polarization modifier (2), having a measuring instrument (35) for measuring the ellipticity and the orientation of the polarization of the light using the Jones formalism.
