Aiman Khan

I am a Ph.D student in Dr. Animesh Datta's quantum information science group at the University of Warwick (2018-present). I completed my integrated masters degree in physics from the Indian Institute of Technology, Roorkee in 2016. Subsequently, I worked with Dr Dipankar Home at the Bose Institute, Kolkata until 2018.

My research at Warwick is focussed on using tools from quantum information science to better understand, theoretically, complex quantum systems. These systems are typically accessible to nonlinear, multidimensional ultrafast spectroscopy using classical light, which in turn has been used to build process tomography protocols for complex dynamics, and construct coherence witnesses. Our fundamental objective is to add to the toolbox linking spectroscopic observables and characterization of the complex systems and dynamics, viewed as open quantum systems coupled to a variety of quantum/classical baths. In this respect, we have proposed a model independent metric of complexity for complex dynamics, based on a witness of quantum dimension, as well as tools from systems identification. In my current project, we are interested in the relationship between theoretical lower bounds on parameters of the complex system with the states of light used in the spectroscopic setup. Our paradigm, we believe, will allow us to decisively choose between various quantum/quasi-classical states of light, as well as the measurement to be performed on these states.
