symmetric evolution, coherence and violation of Leggett-Garg inequalities
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…
Violation of Leggett-Garg type inequalities in a driven two level atom interacting with a squeezed thermal reservoir
Javid Naikoo, Subhashish Banerjee, Arun M. Jayannavar
The violation of Leggett-Garg type inequalities (LGtIs) is studied on a two level atom, driven by an external field in the presence of a squeezed thermal reservoir. The violations…
A study of coherence based measure of quantumness in (non) Markovian channels
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…
Facets of quantum information under non-Markovian evolution
Javid Naikoo, Supriyo Dutta, Subhashish Banerjee
We consider two non-Markovian models: Random Telegraph Noise (RTN) and non-Markovian dephasing (NMD). The memory in these models is studied from the perspective of quantum Fisher i…
