Moderators are staffed during regular business hours New York time and can only accept comments written in English. Liu; A. Simon's condition can be generalized by taking into account the higher order moments of canonical operators   or by using entropic measures. Living organisms green sulphur bacteria have been studied as mediators to create quantum entanglement between otherwise non-interacting light modes, showing high entanglement between light and bacterial modes, and to some extent, even entanglement within the bacteria. These are open questions and the possible answers are highly technical. However, if both spins are measured along the same axis, they are found to be anti-correlated. How big can an object be and still exhibit quantum properties? If we turn the process around so that we transmit sound waves onto the membrane, the flow of over pressure and under pressure caused by the sound wave will push and pull on the membrane and cause it to move. This means that the random outcome of the measurement made on one particle seems to have been transmitted to the other, so that it can make the "right choice" when it too is measured.
