DEVICE FOR QUANTUM RANDOM NUMBER GENERATION AND METHOD FOR VERIFICATION OF PRIVACY OF RANDOM NUMBER SEQUENCES GENERATED BY MEANS THEREOF

Abstract: the invention relates to device for quantum generation of random numbers comprising a light source () with fixed polarization and a polarization splitting element () optically connected thereto, having a first output () corresponding to vertical polarization and a second output () corresponding to horizontal polarization, and a first detector () optically connected to the first output () of the polarization splitting element () and a second detector () optically connected to the second output () of the polarization splitting element (), a generating module () having a first input () connected to the output of the first detector () and a second input () connected to the output of the second detector (), and a two-state output (), the generating module () configured to generate on the two-state output () bits having a value of 1 upon receiving a signal on the first input () and bits having a value of 0 upon receiving a signal on the second input (), characterized in that the light source () is connected to the polarization splitting element () via a multi-state polarization modulator () controlled by a digital or analog signal generated by a control electronics () connected to the multi-state polarization modulator ().
