It could be used for FTL comms if you can figure out how to choose the outcome of a measurement before performing a measurement, which isn't something that I know how to do.
For example consider a lasing medium but without mirrors, that was excited. There is a range of wavelengths (or outcomes) it could emit. However in a laser a specific wavelength (or wavelentghs) are selected for by the mirrors. A photon of a specific wavelength in the optical gain wavelength range cans stimulate the excited atom to emit the same wavelength.
So there exist conditions where the outcome of a quantum transition can be selected for (stimulated emission in this case).
There is an article that proclaims to do precisely that with a pair of phosphorescent samples, simultaneously irradiated by entangled light. They then arbitrarily call one sample the "master" and the other the "slave" sample.
They claim to observe simultaneous emission from the "slave" sample while stimulating emission at the "master" sample, even when separated at large distances in different places.
The authors themselves highlight this apparent violation of the "no-communication theorem" (which is never proven, only postulated), and how it apparently contradicts conventional wisdom about the impossibility of FTL communication. They do not however measure exact photon timings.
Curiously, no other group has disclosed attempting to reproduce or published results confirming or contradicting the proclaimed measurements (which is relatively cheap to execute).
Sigh 202024 and humans still wrestling with the basics.
