Quantum random number generator sets benchmark for size, performance

Posted by in categories: computing, encryption, quantum physics, security

As pervasive as they are in everyday uses, like encryption and security, randomly generated digital numbers are seldom truly random.

So far, only bulky, relatively slow quantum random generators (QRNGs) can achieve levels of randomness on par with the basic laws of quantum physics, but researchers are looking to make these devices faster and more portable.

In Applied Physics Letters, scientists from China present the fastest real-time QRNG to date to make the devices quicker and more portable. The device combines a state-of-the-art photonic integrated with optimized real-time postprocessing for extracting randomness from quantum entropy source of vacuum states.
