It looks like an old PC, but this bleeding-edge 'server' may well save us from hackers causing chaos in a post-quantum computing world — 4.1Gb/s 'rackable' quantum random number generator brings entropy to the data center

Visualization of a random number generator based on quantum fluctuations.

• Fraunhofer introduces quantum random generator targeting future cryptographic security challenges
• Q-Dice uses vacuum fluctuations instead of software algorithms for randomness
• New system delivers over 4 Gbit/s quantum-generated random number output

As concerns grow about the security implications of future quantum computers, researchers continue searching for stronger sources of cryptographic protection.
