No. Quantum cryptography, key distribution, etc. all rely on the ability of communicators to exchange objects like qbits or entangled photons. Properly designed, this provides a guarantee (backed by the Uncertainty Principle) that the communication can't be intercepted. Needless to say, I can't send you a photon over the internet. And, any attempt to send a digital representation of one suffers because digital data can be read non-destructively.
Basically a quantum crypto based network would need, at a minimum, physical fiber optic links between the participants.
