• Abstract: We study the wave-particle duality in a general Mach-Zehnder interferometer with an asymmetric beam splitter from the viewpoint of quantum information theory. The correlations(including the classical correlation and the quantum correlation) between the particle and the which-path detector are derived when they are in pure state or mixed state at the output of Mach-Zehnder interferometer. It is found that the fringe visibility and the correlations are effected by the asymmetric beam splitter and the input state of the particle. The complementary relations between the fringe visibility and the correlations are also presented.

  Atom interferometers provide a powerful tool for measuring physical constants and testifying fundamental physics with unprecedented precision. Here, we report on realizing a Ramsey-Bord'e interferometer of coherent matter waves dressed by a moving optical lattice in the gravity direction. Our findings agree well with theoretical simulations, paving the way for high-precision interferometry with ultracold atoms.

  We show that time-asymmetries in the cross-correlations of photons corresponding to different polarizations can be exploited to probe quantum coherent transport mechanisms and steady-state coherence properties. Our results put forward photon correlation asymmetry as a promising approach to investigate coherent contributions to excited-stated dynamics in molecular aggregates and other many-site quantum emitters.

  We consider a prototype light-harvesting heterodimer exhibiting coherent and collective exciton-vibration interactions. We show that coherent vibronic mechanisms strongly affect the asymmetries characteristic of time-resolved photon cross-correlations. We discuss how such second-order correlation asymmetry establishes important connections between coherent vibronic interactions, directional exciton population transport, and violation of quantum detailed balance.

  We propose an interferometric method to probe pair correlations in a gas of spin-1/2 fermions. The method consists of a Ramsey sequence where both spin states of the Fermi gas are set in a superposition of a state at rest and a state with a large recoil velocity. The off-diagonal long-range order is directly reflected in the behavior of the interferometric signal for long interrogation times.

  Quantum entanglement between an interfering particle and a detector for acquiring the which-path information plays a central role for enforcing Bohr's complementarity principle. Here we find an equality for quantifying the relation between this entanglement and the fringe visibility. We experimentally demonstrate this relation with a superconducting circuit, where a resonator serves as a which-path detector for an interfering qubit.
