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 anyone know precisely which two properties of photons have the uncertainty relation for polarisation? I'm not sure if it's the horizontal/vertical components of polarization, the rectilinear/diagonal schemes of polarization, or something else entirely like spin...
