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…
Temporal self-similarity of quantum dynamical maps as a concept of memorylessness
Shrikant Utagi, R. Srikanth, Subhashish Banerjee
The problem of defining quantum non-Markovianity has proven elusive, with various in-equivalent criteria put forth to address it. The concept of CP-indivisibility and the hierarchy…
Impact of photon addition and subtraction on nonclassical and phase properties of a displaced Fock state
Priya Malpani, Kishore Thapliyal, Nasir Alam +3
Various nonclassical and quantum phase properties of photon added then subtracted displaced Fock state have been examined systematically and rigorously. Higher-order moments of the…
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…
Manipulating nonclassicality via quantum state engineering processes: Vacuum filtration and single photon addition
Priya Malpani, Nasir Alam, Kishore Thapliyal +3
The effect of two quantum state engineering processes that can be used to burn hole at vacuum in the photon number distribution of quantum states of radiation field are compared us…
