Will this information broadcast machine work?

On the Earth Professor Strange has set up a very powerful laser mounted on computerized motor. As shown in the attached diagram, the laser is used to transmit information from Earth to planet X and planet Y which are 2 light years away from each other.

The laser is used to relay message from Earth to both the planets by rotating base, rate of rotation and angle. Based on delays between two photons received at respective planets' sensors the message is decoded.

Will this information broadcasting machine work as intended?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

This setup looks interesting. It is not clear to me how the information is being transmitted and decoded. Could you please elaborate on it? On which planet is the person who is measuring the delay?

Is this setup related to the concept that a laser spot can move faster than light?

"On which planet is the person who is measuring the delay?" Message is being transmitted from Earth and received at both Lab on planet x & y. Decoding is based on simple mechanism where based on 2 different but predetermined length of delay period (between receiving photons) either dot or line is registered and message is decoded. "Is this setup related to the concept that a laser spot can move faster than light?" Yes.

I didn't see this note until just now. I didn't know you were still contributing to Brilliant.

Give me more time to think about it.
