Pure State Transformations under Block Coherence
Dipayan Chakraborty, Priyabrata Char, Indrani Chattopadhyay +1
Block coherence provides a natural generalization of standard quantum coherence by treating superpositions across different subspaces as a resource. This work studies deterministic…

Catalytic Enhancement of Coherence in Noisy Quantum Channels and Characterization of Strictly Incoherent Operations
Priyabrata Char, Dipayan Chakraborty, Indrani Chattopadhyay +1
In realistic quantum information processing tasks, quantum states are inevitably affected by environmental noise, leading to decoherence and degradation of useful quantum resources…
