It seems clear from Bell's 1986 article "Six possible worlds of quantum mechanics" (reproduced in J.S. Bell, Speakable and Unspeakable in Quantum Mechanics, 2nd ed., 2004) that he considered the pilot wave theory a radical, but also valid and simple potential solution to the wave-particle duality problem. (My interest in Bohm's theory was piqued when his text was used in my grad school QM course).
I have two questions about the pilot wave theory:
1. Isn't this a form of hidden variable theory? If so, why is the theory not incompatible with experiments demonstrating violation of Bell's inequality, and thus that a QM theory cannot contain a hidden variable component? Is it somehow the "guidance" of particles provided by the pilot wave that makes the pilot wave theory compatible with entanglement?
2. Has there been further theoretical work on the pilot wave theory? Has any theoretical (or experimental) work since Bell's 1986 article cited above either ruled out or made less likely the pilot wave interpretation of quantum mechanics?
