Dear Francesco,
Thank you for your kind comment.
Ok, I will try:
Most of Physics can be understood and makes sense in terms of Classical Physics that people can understand and is what is termed "Local and Real". We can 'see' what is going on and can build a model of it.
Quantum Mechanics, on the other hand, has some strange counterintuitive aspects, with entanglement being the main one that appears to be "spooky action at a distance" as Einstein famously called it. It asserts that particles can cooperate across vast distances instantaneously as if by magic.
Experiments (usually termed EPR experiments, based on the original thought experiment devised by Einstein, Podolsky and Rosen) have been done that appear to confirm that the QM entanglement is actually occurring; however, due to the practical difficulties in performing the experiment there are possible ways that the correlation found in the experiment can be explained Classically, these are called 'loopholes'. Thus entanglement may not be occurring at all.
In order to solve this situation, recently supposed 'loophole-free experiments have been devised in order to settle the answer once and for all. In these experiments, one of the loopholes termed the detection loophole is attempted to be closed by using a Steering Inequality rather than the usual Bell Test or CHSH Inequality that we're used to determine if entanglement is occurring in the original EPR experiments. The Steering Inequality includes non-detects in the statistical calculations so that detector inefficiency cannot be used as a means to explain the experimental result Classically.
My work shows that this loophole has not been closed, and that even when the Steering Inequality is used, the experimental results can be explained Classically. As a result, the main problem with modeling the word in a 'Local and Real' way is overcome, and entanglement is shown not to be occurring. This may then allow the other aspects of QM to be unified with Classical Physics and Relativity.
I hope this answers your question?
Best Regards,
Declan
