Re: And after
It can be instant - transmit a constant stream of entangled radio waves to mars, keep the other half on a loop (the tricky bit*) then change the state of looped photons that are 10:59 minutes old using an input photon as described in the article - the radio photons 1s away from mars change state.. and voila, 1s lag to mars (or anywhere).
* Maybe all that stuff about reducing light down to walking speed in bose-einstein condensates or what have you could make the light containable for a few minutes...
