Could superposition of entangled quanta provide a means to instantaneous communication and computation?
Not instantaneous but enhanced communication and supercomputation. Apparently 2 particles like electrons in a shared orbital have complimentary spins (+/-1/2). If you split them up and send one away then perform a flip or mag field reorientation on the away particle (that’s n operations incl time rev and n-1 spatial) If you then recombine the ‘altered’ particle with its stay at home twin and perform a measurement on the new entangled system you can recover the info about which of n operations was performed on the away particle. ie you have increased the info from 2 bits to n bits A similar technique applied in reverse with an electron in an unknown state would allow you to transmit info to prepare one of your ‘entangled pair’ to this state..as in teleportation (only available for photons or maybe electrons at the moment) Unfortunately the result of this ‘teleportation’ leaves the original particle in an indeterminate state, so you could not clone yourself this way.
