• Abstract: The delayed-choice quantum eraser has been intensively studied for the wave-particle duality of a single photon in an interferometric system over the last decades. Coincidence measurements between quantum erasers have also been applied for the nonlocal quantum feature, satisfying the Bell inequality violation. However, those quantum features have not been clearly understood yet, resulting in the quantum mystery. Recently a coherence approach has been tried for the quantum eraser to unveil the quantum mystery. Here, a phase quantization of higher-order intensity products between coherently controlled quantum erasers is presented using a quarter wave plate-induced phase shift between orthogonal polarization bases of a single photon. Theoretical solutions of both photonic-de-Broglie-wave-like quantum features and nonlocal quantum correlations are presented for further discussions of quantum mechanics.

  We experimentally generate entangled photonic modes by continuously exciting a quantum emitter, a superconducting qubit, with a coherent drive. We show that entanglement is generated between modes extracted from the two sidebands of the resonance fluorescence spectrum. Our approach can be utilized to distribute entanglement at a high rate in various physical platforms.

  We study a model of amplification of quantum transfer and making it directed which we call the quantum ratchet model. The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels. Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.

  Indistinguishability is an essential concept to understanding mysterious quantum features in the view point of the wave-particle duality of quantum mechanics. Here, a pure coherence approach is applied to the nonlocal correlation using coherent photons manipulated for polarization-frequency correlation. The mysterious quantum feature of nonlocal correlation is now coherently understood and may open the door to macroscopic quantum information processing.
