As far as I understand it (I do some research in quantum physics but NOT quantum information), this quantum cryptography works roughly due to the fact that measurement collapses the quantum wavefunction (destroys the nice quantum properties) of the photons being transmitted.
However recent work shows that not all quantum measurements have to collapse the wavefunction. Thus, there may already be a chink in the QC armour.
