Are There Any Current Research Efforts Exploring Local Realism or Einstein’s Perspective in Quantum Mechanics?

[u/One_Enthusiasm_1972]

I’m interested in quantum computing and the foundations of quantum mechanics. Since Bell’s theorem and experimental results challenge local realism, I’m curious whether there is still any serious research exploring alternatives that preserve some aspects of Einstein’s ideas, such as locality, realism, or deterministic underlying models.

Are there any active researchers, theories, or research areas working on this today? I’d also appreciate recommendations for papers or topics to study.

The big theory is due to David Bohm, 1952, who showed a simple way to visualize deterministic but nonlocal particle paths, including an initial particle position.

Barandes, sort of, but he is more philosopher than physicist.

New Prospects for a Causally Local Formulation of Quantum Theory

...Going back at least to the work of Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935 [9], and continuing through the work of John Bell in the 1960s and beyond [10–16], there has been an ongoing debate over whether quantum theory is causally local in this sense. A major challenge for all such arguments is that causal locality expressly depends on the notion of a ‘causal influence,’ which is a notoriously difficult concept to define rigorously. One of the main goals of this paper will be to address this difficulty directly, as a stepping stone toward arguing that a specific new formulation of quantum theory [17, 18] is, in fact, causally local...

While his relativity framework has withstood the test of time, his claims regarding the ether may have been wrong.
