New quantum random number generator achieves 2 Gbit/s speed

The reliable generation of random numbers has become a central component of information and communications technology. In fact, random number generators, algorithms or devices that can produce random sequences of numbers, are now helping to secure communications between different devices, produce statistical samples, and for various other applications.

Researchers at Toshiba Europe Ltd. recently developed a new quantum random number generator (QRNG) based on a photonic integrated circuit that can be directly integrated in electronic devices. This QRNG, introduced in a paper published in Nature Electronics, can securely and robustly generate random numbers at a remarkable speed of 2 Gbit s-1.

 A new quantum random number generator has achieved a speed of 2 Gbit/s. This breakthrough was made possible by leveraging quantum fluctuations, specifically quantum flickering related to the formation and self-destruction of particles and antiparticles, as well as the associated fields of energy
