After his PhD, he worked as Post-doc fellow at IISER Mohali, India under supervision of Dr Sandeep Goyal. His research interest includes Information-theoretic approach of quantum foundations, Nonlocality, Wave-Particle Duality in Interference Experiment, Wheeler's Delayed-Choice experiment.
Interferometric complementarity is known to be one of the most nonclassical manifestations of the quantum formalism. It is commonly known as wave-particle duality and has been studied presently from the perspective of quantum information theory where wave and particle nature of a quantum system are characterized by coherence and path distinguishability respectively. In this talk, we discuss the effect of noisy detectors on the complementarity relation and show that by suitably choosing the initial quanton and the detector states along with the proper interactions between the quanton and the detectors, one can reduce the influence of noisy environment on complementarity. To demonstrate this, we consider three kind of noises on the detector and study their roles in the saturation of the complementarity relation.
