When two people want to communicate without letting anyone else know what they are saying, they use an encryption. This would be fool-proof, except for the possibility that someone intercepts the encryption key. Communications over the internet get around this possibility by using a method called “public key encryption.” Unfortunately, Public key encryption can be cracked using a quantum computer.
Quantum mechanics is a lot like beer… it’s both the cause of and the solution to all of life’s problems.
Quantum Mechanics can be used to do secure encryption. On this episode of the Titanium Physicists Podcast, we talk about how it’s done!
The guest today is Jesse Brown! He’s a broadcaster, and used to be the host of the “search engine” show. He’s currently canada’s greatest media critic, and he hosts the Canadaland Podcast. It’s a wonderful show.
