Recent times have seen a spurt of research activity focused on “completing” certain wave-
particle duality relations using entanglement or polarization. These studies use a duality …

We theoretically analyze the observations reported in a four-path quantum interference
experiment via multiple-beam Ramsey interference [Phys. Rev. Lett. 86, 559 (2001) …

The interference observed for a quanton, traversing more than one path, is believed to
characterize its wave nature. Conventionally, the sharpness of interference has been …

An interferometer—no matter how clever the design—cannot reveal both the wave and the
particle behavior of a quantum system. This fundamental idea has been captured by …

A quantitative measure of quantum coherence was recently introduced in the context of
quantum information theory. This measure has also been propounded as a good quantifier …

Bohr's principle of complementarity, in the context of a two-slit interference experiment, is
understood as the quantitative measures of wave and particle natures following a duality …

In an asymmetric multislit interference experiment, a quanton is more likely to pass through
certain slits than some others. In such a situation one may be able to predict which slit a …

We formulate a general theory of wave-particle duality for many-body quantum states, which
quantifies how wavelike and particlelike properties balance each other. Much as in the well …

Wave-particle duality in multipath interference is fraught with issues despite substantial
progress in recent years. It was experimentally shown that in certain specific conditions …

According to Bohr's principle of complementarity, a quanton can behave either as a wave or
a particle, depending on the choice of the experimental setup. Some recent two-path …
