Light and Matter Physics
Abhishek’s primary research interest is based on the foundational and the application aspects of nonlocality, mainly motivated by quantum information science, where nonlocality of quantum theory provides many advantages to a range of information processing tasks like secure communication, Device Independent (DI-) Randomness Generation and others.
In this context, he has worked on the certification of nonlocality in nonideal systems and its implications on various information processing tasks. He has been working on the limits on sharing quantum correlations in the sequential Bell scenario.
Apart from this, he is also interested in the dynamics of entangled systems when evolving through noisy channels and their manipulations.
