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…
Entanglement concentration via measurement:- role of imaginarity
Indranil Biswas, Subrata Bera, Ujjwal Sen +2
The role of complex numbers in quantum theory extends beyond mathematical convenience, having recently been formalized as a resource under the framework of the resource theory of i…
Strong nonlocality with more imaginarity and less entanglement
Subrata Bera, Indranil Biswas, Atanu Bhunia +2
Complex numbers are central to the formulation of quantum mechanics, yet their role as a genuine resource is only beginning to be understood. In this work, we demonstrate that quan…
Operational simultaneous correlations in complementary bases of bipartite states via one-sided semi-device-independent steering
Chellasamy Jebarathinam, Debarshi Das, Huan-Yu Ku +2
Recently, a different form of quantum steering, i.e., certification of quantum steering in a one-sided semi-device-independent way, has been formulated [Jebarathinam \etal Phys. Re…
