If I have a list of qubits, is there any formula how to calculate the strength of their entanglement? Something like a correlation coefficient.

It's not clear for me from the post, what is the formula for the 'entanglement coefficient', I would expect something like these are the inputs and this is the how the output is calculated. – sitems Dec 16 '21 at 20:29

Please clarify, since the word "coefficient" doesn't seem to appear anywhere in your question or the one linked in my first comment. – user1271772 No more free time Dec 16 '21 at 20:39

In my mind, quantifying entanglement for a multipartite system is seldom the same as quantifying a single correlation coefficient. – Quantum Mechanic Dec 16 '21 at 21:48

1Hi! Here's another question @user1271772 found that might be of use - How to measure entanglement in an algorithm? – auden Dec 16 '21 at 22:02
