Abstract
Bohmian mechanics reproduces all statistical predictions of quantum mechanics, which ensures that entanglement cannot be used for superluminal signaling. However, individual Bohmian particles can experience superluminal influences. We propose to illustrate this point using a double double-slit setup with path-entangled photons. The Bohmian velocity field for one of the photons can be measured using a recently demonstrated weak-measurement technique. The found velocities strongly depend on the value of a phase shift that is applied to the other photon, potentially at spacelike separation.
Bohmian mechanics [1] is a deterministic interpretation of QM that's empirically equivalent to traditional quantum theory. However, it requires non-locality (instantaneous action across vast distances). From a recent paper [2]: "Bohmian mechanics reproduces all statistical…
