If you can transmit information across branches, wouldn’t you then be able to transmit digital copies of intelligent agents across as well, assuming you have someone on the other end willing to help set up whatever apparatus is needed to run the copy? At that point, don’t you basically have a way to traverse the multiverse?
The problem that you can’t jump anywhere. You can communicate only between two branches which you carefully prepared beforehand—by preparing a ion in a trap and when splitting the branch.
For example, if I did this in the morning today and in the evening one branch has developed misaligned AI and my not (and we have enough trapped ions to send a lot of data) – this mislaigned AI can penetrate my branch. This limitations make risks smaller.
But there can be the ways to bypass this, for example, by finding some natural trapped long-term quantum states (in space? or inside crystals? - Opus said: “Nuclear spins in certain crystals can maintain coherence for remarkably long times—seconds to hours in some cases—because they’re somewhat shielded from electromagnetic noise by their electronic environment. Phosphorus-31 nuclear spins in silicon are a famous example. But even these eventually decohere, and they’re not truly “trapped” in isolation”)
It sounds like inter-branch communication would imply that you could do that. OP does mention that as an application:
7. Superintelligence jumps from one branch to another and also gains more computational power via branch-distributed computations. The exchange of ideas between branches would accelerate science and progress in AI algorithms. This all means that inter-branch communication and the singularity would happen almost simultaneously.
Superintelligent AI will likely appear before this technology matures in the current setup, but branch communication could help AI propagate between branches and increase its dominance on Earth and in the multiverse.
