    Undergrad Quantum cryptography and uncertainty relations

    Thank you for your replies, but perhaps I was a little unclear before - I think I have a reasonable grasp of the method of encryption etc. I'm not so sure about what it is specifically about polarisation that had the uncertainty relation attached to it. Which two variables do not commute? Is it...

    Undergrad Quantum cryptography and uncertainty relations

    Almost all the explanations of quantum cryptography I've come across simply say that the encryption is "protected by the Heisenberg uncertainty principle". I'm having a little difficulty getting any more detail than that without getting way out of my depth (I'm only an A-level student!). Does...
