Quote (timothya @ Aug. 29 2013,20:43) | Quote | The actual energy used is way higher than that which would be required for a single particle pair. First, one must do a large number of pairs to get a statistical ensemble. My understanding (OlegT can chime in here, PM him perhaps) is that the meaning of a wavefunction for a single pair is more problematic than for an ensemble. One must run the instruments that do the detection. One must do specific manipulations to prepare the state in the entangled state. |
My reason for asking concerns the claims made by woo-merchants who witter on about "quantum consciousness" and suchlike. My reading is that the energy required to make any use of the phenomenon would make your brain leak out of your ears. |
Oh, that's only because practical application would need huge numbers of entangled particles, which would have to be carefully kept in isolation to keep them from having interactions that would cause them to lose the entanglements. (Uncontrolled interactions would distribute the entanglement to other particles.)
