Which is a long time. Since it is one big particle in the time dimension then its reaction to any change in energy in the space dimension is instantaneous; it behaves as a single particle.
If both LEDs are tapped onto the same particle in the time dimension then modulating one LED (not on the same breadboard and possibly off planet) with a signal, will transmit the signal to the other LED instantaneously. A macro-entanglement event.
Have a nice day.
Note; No, I make no apology for my mental state.
