[...] they’ll perform with relative ease tasks that are extremely hard for classical computers. Until recently, these tasks were thought to have little real-world use, hence the eye rolls.

But now that Google’s quantum processor is rumored to be close to reaching this goal, imminent quantum supremacy may turn out to have an important application after all: generating pure randomness.
Randomness is crucial for almost everything we do with our computational and communications infrastructure.

“It’s not going to be practical with 50 or 70 qubits,” Aaronson said. Aaronson, for now, is waiting for Google’s system.
If it is, then verifiable quantum randomness from a single quantum device is around the corner.

Random numbers for the quantum computing world, has Crypta Labs really cracked it?

Generating true random numbers for the quantum computing era, or indeed the pre-quantum era, is the aim. Crypta Labs reckon they have cracked it.

A Major Step in Standardization of Quantum Random Number Generators (QRNG)

Pseudo random number generators currently in use seem to provide random bit sequences, but actually these bit sequences have certain patterns, so there is a risk of being hacked. The integration of physical entropy sources in random number generators is the most common method to overcome this security threat.
Quantum physics, on the other hand, is random by essence. Numbers generated by a Quantum Random Number Generator (QRNG) cannot be predicted – QRNG is provably unpredictable. So if a quantum random number generator is used in a security system, even a fast supercomputer with a fast arithmetic operation cannot predict the random bit sequences used by this security system.

The newly consented draft recommendation, which is expected to be approved within 2019, deals with a common architecture for quantum entropy sources. This common architecture will allow suppliers and users to make a clear and simple distinction between QRNGs and other physical random number generators called True Random Number Generators (TRNGs).

“The QRNG standard will give the ICT industry a random number generator with proven unpredictability. Success for this standard would be its adoption by most or all QRNG vendors as well as some national security agencies.“ says Grégoire Ribordy, CEO of ID Quantique.
