Quantum encryption or cryptography is a specialized niche. I am not sure how a classical system can be robust against interlopers in the way a quantum channel is, for such would results in a disruption of the wave function. Maybe some clever use of a quantum eraser might get around this.

I view quantum cryptography as mostly hype. Quantum cryptography doesn't solve the problem of authentication which is the main challenge when distributing keys (i.e., ensuring the right person is getting them, rather than merely ensuring they weren't intercepted). The other reason I think it is

Chinese researchers report in the journal Nature that they have used quantum entanglement and a satellite to send a Cryptographic key over a record distance of 1120 Kilometers as securely as the laws of physics allow and do so with unprecedented speed and low error rates. The transmission speed
