Episode 42: Quantum Twins Talk In Code With Jesse Brown.

When two people want to communicate without letting anyone else know what they are stiphy42aying, 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.

One thought on “Episode 42: Quantum Twins Talk In Code With Jesse Brown.

  1. “… Public key encryption can be cracked using a quantum computer.”
    Is the degree of success that can be achieved by quantum computers dependent upon issues in string theory?
    “We claim that our observations add a new twist to discussions concerning the interpretation of quantum mechanics, which we call the cellular automaton (CA) interpretation.” — G. ‘t Hooft

    “String theory clearly appears to be strikingly coherent. What seems to be missing
    presently, however, is a clear description of the local nature of its underlying physical laws. In all circumstances encountered until now, it has been imperative that external fields, in- and outgoing strings and D-branes are required to obey their respective field equations, or lie on their respective mass shells. Thus, only effects due to external perturbations can be computed when these external perturbations obey equations of motion. To me, this implies that we do not understand what the independent degrees of freedom are, and there seems to be no indication that these can be identified. String theoreticians are right in not allowing themselves to be disturbed by this drawback.”
