Many experiments to verify nonlocal interaction and non-classical phenomena using entangled lights were conducted in the 1980s, and many physicists were interested in their unrecognizable correlation. These quantum mechanical effects were used in Aspect's experiments and Bell tests and had a great influence on the interpretation of quantum mechanics. However, their essence, including their “spooky” interaction, is unknown. In this study, we show that entangled light can be expressed by the product of electric fields and that the same result as quantum mechanics can be obtained using the product form.
