How does LHV explain quantum entanglement swapping?

In summary, LHV theory attempts to explain the phenomena of quantum entanglement swapping and two-photon interference without the photons ever meeting at the same time-space/place by proposing hidden variables that determine the outcome of these experiments. However, various LHV models have been proposed and none have been proven to fully explain these phenomena.

how does/would LHV (local hidden variables) theory explain the phenomena of:

1. quantum entanglement swapping (where Alice and Bob never meet, and Charlie/Victor is still able to entangle their photons)
2. two-photon interference without the photons ever meeting at the same time-space/place

It depends on what LHV model you have in mind:

1. What is LHV?

LHV stands for "local hidden variable" and is a theoretical explanation for the behavior of particles in quantum entanglement swapping experiments.

2. How does LHV explain quantum entanglement swapping?

LHV proposes that particles have predetermined properties, or "hidden variables", that determine their behavior and interactions with other particles. In quantum entanglement swapping, these hidden variables can account for the seemingly instantaneous communication between entangled particles.

3. What are the limitations of LHV in explaining quantum entanglement swapping?

LHV is unable to fully explain the phenomenon of quantum entanglement swapping, as it cannot account for the non-local correlations observed between entangled particles. This means that there must be some other factor at play beyond predetermined hidden variables.

4. How does LHV compare to other theories, such as quantum mechanics, in explaining quantum entanglement swapping?

LHV is considered a classical theory, while quantum mechanics is a more accepted explanation for the behavior of particles in quantum entanglement experiments. Unlike LHV, quantum mechanics can fully account for the non-local correlations observed in entangled particles.

5. Is there any evidence to support LHV's explanation of quantum entanglement swapping?

There is currently no empirical evidence to support LHV as a complete explanation for quantum entanglement swapping. Many experiments and observations have shown that quantum mechanics provides a more accurate and comprehensive understanding of this phenomenon.
