It thus appears that Newton’s equation of motion could be derived in this fashion from electrodynamics, and it has been shown that the relativistic version of the equation of motion also n ...

Experimentally, the quantum-state purity can be measured as the visibility of the Hong-Ou-Mandel interference [30] with two independent identical heralded singlephoton sources ...
