What CISOs Should Know About Quantum Computing

Quantum computing is quickly moving from the theoretical world to reality. Last week Google researchers revealed a new quantum computing processor that the company says may beat the best benchmark in computing power set by today's most advanced supercomputers.

That's bad news for CISOs because most experts agree that once quantum computing advances far enough and spreads wide enough, today's encryption measures are toast. General consensus is that within about a decade, quantum computers will be able to brute-force public key encryption as it is designed today.

Here are some key things to know and consider about this next generation of computing and its ultimate impact on security.
