That is an interesting observation because there is a flip side to it. I can sell you some ordinary looking gear that contains a quantum entanglement based eavesdropper. You can have your device in a cave 20 miles below the earth's surface in a bunker running off diesel generators, with no connections outside the bunker, and here I am, watching everything you do.
- ZoFreX 14y agoCan someone with a greater understanding of quantum physics chime in here - is this correct?
- btilly 14y agoIt is not correct. Quantum entanglement is easy to break, and once broken will not re-establish on its own.
- tgb 14y agoHow would you do that? Quantum teleportation requires the transmission of 2 classical bits for every qubit, by the only method I know about.
