- Abstract: Quantum superposition is the cornerstone of quantum mechanics, where
interference fringes originate in the self-interference of a single photon via
indistinguishable photon characteristics. Wheeler delayed-choice experiments
have been extensively demonstrated over the last decades to understand the
complementarity theory of quantum mechanics for the wave-particle duality. The
heart of the delayed-choice experiments is in the mutually exclusive quantum
feature violating the cause-effect relation. Here, we experimentally
demonstrate the violation of the cause-effect relation using coherent photons
for the quantum eraser. Unlike most delayed-choice schemes using undetermined
photons in MZI, the present scheme is for the determined photon for the MZI via
post-measurement controls. The observed quantum eraser is coherently
interpreted to seek the origin of the cause-effect violation.

We find not only the single-photon topological states but also the bands of exotic bound photon pairs arising due to the inherent anharmonicity of qubits.
