Here is a thought experiment: suppose you invented a machine that could produce a steady flow of entangled particles and sent that stream through conduits pointed in opposite directions.
Let's say the machine was in Hawaii and it sent one flow of particles to a laboratory in India and the other flow to a laboratory in the UK.
Now those laboratories are set up with extremely accurate clocks and a double slit experiment into which the particles would flow.
At first both laboratories allow their particular stream of particles to produce wave interference patterns at the their respective double slits.
My question is this: if the laboratory in the UK suddenly decided to detect the slit through which each of the particles it received passed, thus collapsing their particle stream's wave function, would the wave function of the entangled stream of particles at the Indian laboratory appear to inexplicably collapse? Would the Indians simultaneously lose their wave interference pattern?
If so is this not faster than light information exchange? Could the switching back and forth between collapsing and non-collapsing wave function states of the entangled particle steams then act as a kind of faster than light morse code?
