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…
Influence of joint measurement bases on sharing network nonlocality
Amit Kundu, Debasis Sarkar
Sharing network nonlocality in an extended quantum network scenario is the new paradigm in the development of quantum theory. In this paper, we investigate the influence of Elegant…
Measurement dependence can enhance security in a quantum network
Amit Kundu, Debasis Sarkar
Network Nonlocality is an advanced study of quantum nonlocality that comprises network structure beyond Bell's theorem. The development of quantum networks has the potential to bri…
