  Quantum technologies based on the particle nature of a photon has been
progressed over the last several decades, where the fundamental quantum
features of entanglement have been tested by Hong-Ou-Mandel-type
anticorrelation and Bell-type nonlocal correlation. Recently, mutually
exclusive quantum features based on the wave nature of a photon have been
investigated to understand the fundamental physics of mysterious quantum
correlation, resulting in deterministic and macroscopic quantum technologies.
Here, we study the quantum natures of paired photons acting on a beam splitter,
where mutual coherence plays a major role. Unlike current common understanding
on anticorrelation, bipartite entanglement between paired photons does not have
to be probabilistic or post-selected, but can be deterministic and even
macroscopic via phase basis manipulation without violating quantum mechanics.
