Quantum Entanglement Visible to the Naked Eye
- trjordan 17y agoI worked in a lab for a bit that was doing this sort of thing, and it's worth saying that Martinis is a genius. The stuff he's doing is far beyond what other groups are doing, and he manages to pull it off in incredibly elegant ways. Coupling two qubits like this is impressive, to say the least. Planar qubits have the advantage of scale when it comes to fabrication, so if this group can figure out how to push entanglement to 3, 4, or more devices, they'll have a huge advantage over other technologies (e.g. ion trapping).
- davepeck 17y agoSo: what does it look like?
- michaelneale 17y agoIf you were to use this entanglement to transport information (by periodically changing the flow, from that case) - would the change of the entangled thing be instantaneous or limited to speed/distance between them by C? (excuse my naivete).
- Devilboy 17y agoYou can not transmit information that way unfortunately. I found this link: http://everything2.com/title/Quantum+entanglement+and+faster+than+light+communication http://everything2.com/title/Quantum+entanglement+and+faster...

- mleonhard 17y agoDo you know if entangled particles could be used as a shared random bit source?
- sp332 17y agoSure, that's how quantum key exchange works. http://en.wikipedia.org/wiki/Quantum_encryption#BB84_protocol:_Charles_H._Bennett_and_Gilles_Brassard_.281984.29 http://en.wikipedia.org/wiki/Quantum_encryption#BB84_protoco...
