Faster than Light Communication

If the following is true, then faster than light communication is feasible.

1. Quantum entangled photons are emitted pairs, or structures.

2. Any change in one will instantaneously affect the other, no matter what the distance between them. For this design, the change will be annihilation. One theory states that simply measuring one photon will collapse the wave front. Reflection or absorbsion should also work.

An emission source is required. It would be fortunate if a star would suffice. 

The transmitter can be any distance from the emitter, the receiver on the opposite side must be slightly farther away. Let's say they are both 10 light years away from the emitter.

The receiver is measuring the photons issuing from the emitter. 10 years ago, two sets of entangled photons left the emitter. They arrive at the transmitter first, who then annihilates enough photons to be detected by the receiver. The receiver measures the change in flux density immediately after they were annihilated by the transmitter. 

Thusly, an instantaneous digital data stream can be established over a distance of 20 light years, delayed only by how much farther away from the emitter the receiver is than the transmitter.

The advantage of using a star is that they have been emitting photons for millions of years. All that is required is that the receiver be able measure the change in flux density created by the transmitter. Only annihilated entangled photons will be useful. They don't have to be on opposite sides of the star, just preferably equidistant from it. 

SETI hunters might want to look to see if an alien intelligence is modulating a star in order to communicate. I would start with the hydrogen spectral line, but maybe a broad spectrum works better. 

If a star is impractical, then a laser emitter should work. If annihilation is impractical, any method that will allow a receiver to measure a statistical change  will do.
