Universal quantum uncertainty relations between non-ergodicity and loss of information
Natasha Awasthi, Samyadeb Bhattacharya, Aditi Sen De +1
We establish uncertainty relations between information loss in general open quantum systems and the amount of non-ergodicity of the corresponding dynamics. The relations hold for a…
Static and dynamical quantum correlations in phases of an alternating field XY model
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We investigate the static and dynamical patterns of entanglement in an anisotropic XY model with an alternating transverse magnetic field, which is equivalent to a two-component on…
Distribution of Bell inequality violation vs. multiparty quantum correlation measures
Kunal Sharma, Tamoghna Das, Aditi Sen De +1
Violation of a Bell inequality guarantees the existence of quantum correlations in a quantum state. A pure bipartite quantum state, having nonvanishing quantum correlation, always…
Information complementarity in multipartite quantum states and security in cryptography
Anindita Bera, Asutosh Kumar, Debraj Rakshit +3
We derive complementarity relations for arbitrary quantum states of multiparty systems, of arbitrary number of parties and dimensions, between the purity of a part of the system an…
Cumulative quantum work-deficit versus entanglement in the dynamics of an infinite spin chain
Himadri Shekhar Dhar, Rupamanjari Ghosh, Aditi Sen De +1
We find that the dynamical phase transition (DPT) in nearest-neighbor bipartite entanglement of time-evolved states of the anisotropic infinite quantum XY spin chain, in a transver…
Patterns of Genuine Multipartite Entanglement in Frustrated Quantum Spin Systems
Lavisha Jindal, Ameya Deepak Rane, Himadri Shekhar Dhar +2
We investigate the behavior of genuine multipartite entanglement of paradigmatic frustrated quantum spin systems. We consider six different spin models, whose frustration ranges fr…
