The invention relates to a device for quantum random number generation (QRNG) and a method of verifying the privacy of the generated random sequences.
The device uses a light source with fixed polarization, a polarization-splitting element dividing the beam into two channels, and a set of detectors that register vertically and horizontally polarized photons. Signals from the detectors are processed by a generating module that assigns binary values and produces a sequence of random bits.
The innovative aspect of the solution is the application of a multi-state polarization modulator controlled by an electronic system, which increases control over the generation process and enables ongoing verification of the privacy of the obtained random sequences.
