- Abstract: Photon indistinguishability is an essential concept to understanding
mysterious quantum features from the viewpoint of the wave-particle duality in
quantum mechanics. The physics of indistinguishability lies in the manipulation
of quantum superposition between orthonormal bases of a single photon such as
in a quantum eraser. Here, a pure coherence approach is applied for the
nonlocal correlation based on the polarization-frequency correlation of
Poisson-distributed coherent photon pairs to investigate the role of
measurements. For this, a gated heterodyne-detection technique is adopted for
coincidence measurements between space-like separated delayed-choice quantum
erasers, resulting in an inseparable basis product between them. For this
coherently induced inseparable basis product, polarization-frequency correlated
photon pairs are selectively measured through a dc-cut ac-pass filter to
eliminate unwanted group of polarization-product bases. Finally, the Bell
inequality violation is numerically confirmed for the coherence solutions of
the nonlocal correlation.
