Thank you John From: a...@listbox.com To: a...@listbox.com Subject: RE: [agi] Couple thoughts Date: Tue, 3 Mar 2015 10:40:46 -0500 The more accurate term is “quantum encryption network” verses “quantum network” since it’s not transmitting data by entanglement or other means it’s using quantum encryption (QKD). So some of it is hype.
