  Recently, a new interpretation of quantum mechanics has been developed for
the wave nature of a photon, where determinacy in quantum correlations becomes
an inherent property without the violation of quantum mechanics. Here, we
experimentally demonstrate a direct proof of the wave natures of quantum
correlation for the so-called coherence de Broglie waves (CBWs) using
sub-Poisson distributed coherent photon pairs obtained from an attenuated
laser. The observed experimental data coincides with the analytic solutions and
the numerical calculations. Thus, the CBWs pave a road toward deterministic and
macroscopic quantum technologies for such as quantum metrology, quantum
sensing, and even quantum communications, that are otherwise heavily limited
due to the microscopic non-determinacy of the particle nature-based quantum
mechanics.
