There is a saves about "Electron Entanglement" on the FP currently.
This reminds me of one old research I had committed before my homework crashed me.
That is, to find a phenomenon in TPT that is similar to real world's quantum entanglement,
as being an instantaneous effect for information transfer without limitation on particle's position.

I am aware of the existence of WIFI, PRTI as medium of position-free signal transmission,
yet they are unfit for subframe usage,
as LBPHacker has once proven that WIFI only transfer signal once per two frame,
(PS: or have you fixed it?)
and my own experiment show that PRTI do not transfer signal in a stable manner,
but rather refuse to give SPRK occasionally.

Then it makes sense to seek for another form of instantaneous position-free medium.

One suggested solution is to make use of singularity(not SING) in tpt.
Such elements must have the property of being the sole existence in an simulation.
The elements fulfilling this criteria are SPWN and SPWN2.
If you spawn 1 px. of SPWN using CRAY, you cannot spawn another px. of SPWN.
(PS: strangely, CRAY created SPWN will not spawn STKM)
As a result, a CRAY with lower particle ID will spawn SPWN, stopping later CRAY from spawning SPWN.
If you put a controller that controls the existence of SPWN in position A,
you can have a receiver at position B to check for existence of SPWN by trying to spawn SPWN subframely.
If the CRAY(SPWN) at B successfully spawn SPWN, you know there is no SPWN at A.
(PS: CRAY at B must has a higher particle ID than A's controller for 0 latency transmission)
This creates a quantum-like entanglement across A and B that has a bandwidth of 1 bit/frame.

There is a lot of limitations on using SPWN and SPWN2 as the bandwidth is low,
and there can only be a pair of them in one save that it cannot be of common use.

But you get the initial idea of one form of pseudo-quantum-entanglement.
The essence of this form of entanglement is secretly accessing shared memory of TPT(i.e. global variables)
to achieve the effect of position-free transmission.
I had stopped here, but I predicted that this idea can be expanded to a more common use.

(PS: This article has to be stopped, I got a lot of revisions and homeworks, I will come back when the semester ends if I am still alive by that time)

Good idea, you can take this as your research topic.
Just that I will not be participating as the only mod I use for tpt is tptmp and I don't plan to use other mods
I prefer to do my researches on vanilla tpt so that everyone can enjoy its benefit.
