Experimental Demonstration of Entanglement?
In many papers about entangled sources, they use an experimental setup like this one to demonstrate their entanglement:
The setup involves measuring coincidences at the detectors at various angles of ...

How efficient are coincidence counting techniques?
Obviously there is a limitation as to how well experimental configurations that depend on coincidence counting can efficiently remove the noise present at any given experiment. This leads me to ...

How far are we from actual test that gravity is quantum?
As we all know, probing the Planck scale directly is still far beyond our current technologies. But I've heard that proving that in fact gravity is quantum should be much easier and we are not that ...

IBM Quantum Circuit output probabilities for single Hadamard gate
I am new to using the IBM Quantum Emulator, and I encounter this result which I don't understand:
The input is a single 0 bit that is passed into a Hadamard gate (click the picture to enlarge). I ...

Are quantum fluctuations observable?
I know I am asking out of my limits, but i felt relaxed thinking about this.
Now I read somewhere about quantum fluctuations (that energy can be generated in randomly at two positions where total sum ...

What are large, 'artificial' atoms for? When making 'quantum' devices?
Several recent things I have read say that 'quantum' materials taking advantage of entanglement, among other quantum properties, work better if very large, synthetic/artificial 'atoms' are used, which ...

Delayed Choice Quantum Eraser variation results
If we were to start with the delayed choice quantum eraser setup in the attached image, what would the interference pattern look like for the photons at D0 if D3 and D4 were eliminated (and the two ...

Which experiment can differentiate a statistical mixture from a superposition state?
I am in trouble with polarization and entanglement.
Let's consider three cases :
Case 1) : Statistical mixture of $|H\rangle$ and $|V\rangle$ polarized photons
Case 2) : Photons in a superposition ...

What is the effect of magnetic fields applied to an entangled pair of particles?
Just curious...if we can create a pair of entangled particles and position one of them in a strong magnetic field would it have as a consequence that we can't change the spin of the other because that ...

Is the speed of quantum entanglement interaction greather than $c$? [duplicate]
How much time should not elapse between measurements of e- and e+ spin computed at a distance ot 1km to not detect effects of the entanglement? There should be a finite speed? Maybe greater than $c$?...

Can we create "asymmetric" EPR pairs in experiments?
Asymmetric here is just for lack of a better word.
What I am looking for are experiments that can create a simple EPR pair but without 50% 50% chance of each state.
As I understand from standard ...
