Using no entanglement to communicate faster than light




In some sense, this is a climb-down. It follows because entanglement is not necessary! It requires nothing fancy to do better than 1 bit@liight-speed! If you capture an image in a telescope, you get lots of bit at once! If you focus at a spot and take the image MANY TIMES, THE SPEED OF INFORMATION CAN EXCEED LIGHT SPEED. If image is of bits, not any image, you are communicating faster than light. That is what is happening in entanglement write-up – entanglement makes it harder to see, and indeed the method is a different way to communicate. But not faster in any way.

Assuming entangle information takes zero time, imagine groups A and B distant by 4 light years. You can get the state of sending particles at once but not even fraction of a bit before 4 years. The pattern makes only sense after applying that image.

Once started, pipelining is possible.

So is earlier methods good for anything? Automatic delay-proof encryption! 

Does it mean that faster communication is dead? My work so far. I have no idea of how to do it, if at all, without sacrifice of entanglement proportional to the length of message but doing so attacks a theorem that it can’t be done. That is certainly Nobel Prize work i.e. highly unlikely to work except at high probability, which gets around the no-go theorem.
