To explore America’s “transition to a post-quantum world,” the Washington Post interviewed U.S. federal official Nick Polk, who is focused on national security issues including quantum computing and is also a senior advisor to a White House federal chief information security officer):
The Washington Post: The U.S. is in the early stages of a major shift focused on bolstering government network defenses, pushing federal agencies to adopt a new encryption standard known as post-quantum cryptography that aims to prevent systems from being vulnerable to advanced decryption techniques enabled by quantum computers in the near future…
Nick Polk: We’ve been using asymmetric encryption for a very long time now, and it’s been ubiquitous since about 2014, when the U.S. government and some of the large tech companies decided that they’re going to make it a default on most web browsers… Interestingly enough, regarding the post-quantum cryptographic standards being developed, the only thing that’s quantum about them is that it has “quantum” in the name. It’s really just a different type of math that’s much more difficult for a quantum computer to be able to reverse-engineer. The National Institute of Standards and Technology is looking at different mathematical models to cover all their bases. The interesting thing is that these post-quantum standards are actually being used to protect classical computers that we have now, like laptops…
Given the…
