Quantum Random Number Generator (QRNG) doesn't rely on mathematical algorithms. QRNG generates randomness from a true quantum source, thereby creating a greater degree of unpredictability and security for every application.
QRNG is an incredibly advanced deep technology that uses a combination of semiconductor technology, optoelectronics, high-precision electronics, and quantum physics to produce randomness at the very deepest level possible. This quantum-based process provides the highest possible quality of entropy for your most critical systems.
Traditional random number generators, such as PRNGs and TRNGs, are based on deterministic logic. When all the input variables are known, they can reproduce their outputs. This predictability introduces entropy limitations, leaving systems exposed to potential threats.
QRNGs are innovative because they utilize the inherently random properties of quantum physics that offers unpredictable scientifically proven randomness by

A laser emits a stream of photons, the fundamental particles of light.
These photons are refined to a single-photon level using variable optical attenuators.
Each photon is directed to a Single Photon Detector (SPD).
Using external time references, the "Time-of-Arrival" of individual photons is recorded to generate random numbers.
The following diagram depicts the step-by-step process from photon generation to random number output that is unconditionally secure. First, light is produced from a laser source, then attenuated down to almost a single-photon level by a variable optical attenuator.
Once the photons have been attenuated, they are sent onto an SPD (Single Photon Detector), and the time bin at which the photon detections are recorded through an external time reference.
Since photons exhibit quantum behavior, the detection time bin can never, in principle, be known in advance, even though we are often able to know the other aspects of the experiment (preparation, propagation, and detection). The randomness finally collapses into a specific time bin only at the point of detection.
