Quantum random number generators (QRNGs) are widely recognised as the most effective solution for generating true random numbers, essential in cryptography and other applications requiring the highest standards of randomness.
Several quantum phenomena have been explored for QRNGs, such as:
- A single photon traveling along two paths and being detected by single-photon avalanche diode photodetectors.
- Detection of amplified spontaneous emission (ASE) signals.
- Measuring photon arrival times.
- Vacuum state fluctuations.
- Laser chaotic signals.
- Phase noise of laser diodes, as explored in this study.
QRNGs harness the unique properties of quantum physics to create true randomness. Unlike traditional methods based on predictable algorithms, QRNGs are entirely unpredictable, making them significantly more secure.
A study* titled “Long term experimental verification of a single chip quantum random number generator fabricated on the InP platform” presents the findings of an experimental evaluation of a quantum random number generator circuit tested over 300 minutes using a single chip fabricated on the InP platform.
This cutting-edge technology is already transforming industries by securing:
- Online transactions and communications
- Sensitive patient data and research
- Fair and unbiased randomization processes.
By adopting QRNGs, sensitive information is better safeguarded from cyber threats, ensuring robust security for critical systems.
Initiatives like HellasQCI are positioning Greece at the forefront of quantum innovation. By leveraging QRNGs and other quantum technologies, Greece is contributing to the European Quantum Communication Infrastructure (EuroQCI) and safeguarding critical systems in Greece and across Europe.
