Since its inception, quantum coherence has been linked by research groups in the world with other quantum resources like non-locality, non-Markovianity, entanglement, and quantum correlations. We will address how these resources can be utilized in quantum communications. We will address new quantum information processing tasks in which quantum coherence can be used as a resource. Their possible implementations in photonic devices will be explored in collaboration with RRI. We will develop a method to detect and measure quantum states both for pure as well as for mixed states. Using quantum interference setup, we plan to measure entanglement with photonic qubits.

We will explore how to formulate new uncertainties relations using other quantifiers of uncertainties and errors where standard deviation is not well defined. In addition, we will explore how the uncertainty relations for quantum coherence in two incompatible bases can have applications in entanglement detection, quantum speed limit, quantum control etc.
