Interplay of nonlocality and incompatibility breaking qubit channels
Swati Kumari, Javid Naikoo, Sibasish Ghosh +1
Incompatibility and nonlocality are not only of foundational interest but also act as important resources for quantum information theory. In the Clauser-Horne-Shimony-Holt (CHSH) s…
Projective measurements under qubit quantum channels
Javid Naikoo, Subhashish Banerjee, A. K. Pan +1
The action of qubit channels on projective measurements on a qubit state is used to establish an equivalence between channels and properties of generalized measurements characteriz…
Distinguishing environment-induced non-Markovianity from subsystem dynamics
Subhashish Banerjee, Javid Naikoo, R. Srikanth
Quantum non-Markovianity modifies the environmental decoherence of a system. This situation is enriched in complex systems owing to interactions among subsystems. We consider the p…
Non-Markovian channel from the reduced dynamics of coin in quantum walk
Javid Naikoo, Subhashish Banerjee, C. M. Chandrashekar
The quantum channels with memory, known as non-Markovian channels, are of crucial importance for a realistic description of a variety of physical systems, and pave ways for new met…

Javid Naikoo, Swati Kumari, A. K. Pan +1
We report an unusual buildup of the quantum coherence in a qubit subjected to non-Hermitian evolution generated by a Parity-Time () symmetric Hamiltonian, which is re…
Quantumness of channels
Javid Naikoo, Subhashish Banerjee, R. Srikanth
The reliability of quantum channels for transmitting information is of profound importance from the perspective of quantum information. This naturally leads to the question as how…

Javid Naikoo, Subhashish Banerjee
We make a detailed analysis of quantumness for various quantum noise channels, both Markovian and non-Markovian. The noise channels considered include dephasing channels like rando…
Interplay between nonclassicality and symmetry in an effective two level system with open system effects
Javid Naikoo, Subhashish Banerjee, Anirban Pathak
A three level atom in configuration is reduced to an effective two level system, under appropriate conditions, and its symmetric properties are investigated. Thi…
