Engineers need to start studying the trade-offs of different post-quantum cryptography techniques so they are ready when quantum computers arrive.
No one is sure when (or really even if) quantum computers will become practically useful, but some experts believe that within 10 years a quantum computer could be capable of breaking today’s cryptography. Google, Microsoft, IBM and Intel, as well as numerous well-funded startups, are making significant progress toward quantum computers. And scientists around the world are investigating a variety of technologies to make quantum computers real.
