# Delay in signaling between entanglement particles

I know that there isn't any delay that depends on the distance between particles, by the time it take to signal l to arrive from point a to b , but do there is any small delay that doesn't depends on distance .
like the Minimum distance between two bodies divided by the speed of light .
for example if we would create some kind of interaction domino with couples of entanglement practicals so when measuring one particle t will effect the practical it been entangle to which will interact with another practical and so on like the following draw

in this draw A,A' B,B' C,C' are an couples of entanglement particles , we also know that A' is interact with B and B' with C and so on. I am wondering if would have a lot of couples of entanglement particles so we may measured a delay between the time we measure A till we can observe the result that bigger then the time it take to tell when the piratical has been measured (the time it take the electromagnetic signal to get from the first location to the last one )

A “practical” is a hands-on exam or a lab exercise. A “particle” is a small object or (in QM) a quantized excitation of a corresponding particle field.

Ok i changed it, my mistake my browser is not recognize this word so I changed it

Entangled particles do not operate the way you are picturing them. A particle can only be entangled as part of a single system at a time. That system can be more than 2 particles. But if it is, the statistics change.

There is a specialized mechanism which is called "entanglement swapping". It is "possible" to entangle particle A with particle D' as part of a chain of swaps. The setup is quite complex and those swaps would only occur as a very rare event.

and do you think there is small delay of interaction ?

and do you think there is small delay of reaction ?
Not only is there no evidence for a delay in the reaction, there is no reason to think that there is a reaction.

sorry I meant interaction

I know what you meant, and my answer still stands.
