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?

comment Exploiting the Heisenberg Uncertainty Principle as a means to communicate
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.

comment Exploiting the Heisenberg Uncertainty Principle as a means to communicate
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.

comment Identical fermions in the same quantum state
I am basically stating, "We can distinguish two Hydrogen Atoms from the fact that they are located at different locations." If the two Hydrogen Atoms were to overlap their wave functions, then we can't tell them apart. The exceptions I was talking about was about how Bosons are indistinguishable. I am trying to understand what we can say is different or the same in the most fundamental way possible.

comment Identical fermions in the same quantum state
Okay, so to solidify my understanding, if we consider two electrons in the potential of two hydrogen nuclei, then we have two electrons that are distinguishable because of the fact that the two protons are located at a different locations. Everything technically is distinguishable because of space time itself? With the exception of Bosons? Ex: two photons with same energy that are overlapped traveling the same direction and in phase, or Bose Einstein condensates with atoms all collapsed in the same location with ground state energy?

comment Identical fermions in the same quantum state
Okay, say I have two ions then. Can their remaining electrons be in the same orbital, same energy state, and same spin state? Can this happen if the two ions are separated by a large distance?

comment Identical fermions in the same quantum state
I did not think of the hydrogen as a boson! I guess my question would be if I picked an element that is a fermion, say Lithium atoms?
