Graduated physics major and math minor from Drexel University. I want to study entanglement and how to use it to do quantum teleportation on a larger scale.

comment How does one subtract two light beams?
So are you basically saying that we can use the homodyne measurement technique but to make one beam 180 degrees shifted before combining them together at a beam combiner? So this means I can get x2 - x1

comment Exploiting the Heisenberg Uncertainty Principle as a means to communicate
I am an undergraduate physics student and have not taken graduate level quantum mechanics that uses the trace and notation you've shown here. I do not follow completely, but I get the idea. Are you talking about a single position measurement or multiple measurements in an ensemble of entangled pairs? I believe that the single measurement case, you can't control the outcome. However, I'm not concerned with the single measurement outcome. I'm looking at the standard deviation of multiple position measurements. Does your answer address this and I've missed it completely?

The only equation needed is the standard deviation equation, which everyone knows and the entanglement relation in terms of position and momentum. This is x1 = x2 and p1 = -p2, where x1 is position measurement of particle 1 in Lab A and x2 is position measurement of particle 2 in Lab B. The observables measured is the position and momentum measurement of an atom. There really isn't any other equation needed.

I did mention that Alice makes a measurement on an ensemble of her particles with each of her particles entangled with Bob's particles. Each ensemble represents one bit. Moreover, Alice and Bob agree ahead of time that Alice only measures position and Bob only measures momentum. They also have synchronized clocks and measure at the same time or very close in time interval.
