"Last month Google announced its quantum supremacy, which can solve a mathematical calculation in 200 seconds that would take a supercomputer 10000 years. This computing ability not only opens doors to radical new inventions, but also raises the prospects of new security threats. Until now, the security depends on cryptographic tools (RNG/TRNG) and symmetric /asymmetric encryptions, which can have a lifespan of 10-15 years. These securities measures will be potentially easily cracked by quantum computing, if directed at them.
The solution to this is to apply new and hybrid models of cryptography known as quantum random number generator (QRNG) along with the other three pillars of security (software, network and cloud)." – Satyajit Sinha
