Decoherence-free subspaces and Markovian revival of genuine multipartite entanglement in a dissipative system
Shubhodeep Gangopadhyay, Vinayak Jagadish, R. Srikanth
We investigate the dynamics of genuine multipartite entanglement (GME) in a system of qubits () collectively interacting with a common zero temperature bosonic bath char…
Effect of Weak Measurement Reversal on Quantum Correlations in a Correlated Amplitude Damping Channel, with a Neural Network Perspective
Venkat Abhignan, Bidyut Bikash Boruah, R. Srikanth +1
We study the evolution of quantum correlations in Bell, Werner, and maximally entangled mixed states of two qubits subjected to correlated amplitude-damping channels. Our primary f…
Analytical classification of Majorana zero-mode spatial profiles in extended Kitaev chains: probability maxima can shift inward
Vijay Pathak, Vaishnav Mallya, Sujit Sarkar
Topological phases in one-dimensional superconducting systems are commonly characterized by symmetry-protected invariants. These invariants determine the number of Majorana zero-en…
Quantum steganographic protocols using degenerate and entanglement-assisted quantum codes
Sanjoy Dutta, Nihar Ranjan Dash, Subhashish Banerjee +1
Steganography is the art of concealing secret information by embedding it in an apparently innocent-looking message. Quantum steganography applies the principles of quantum mechani…
Dissipation in fermionic two-body continuous-time quantum walk under the steepest entropy ascent formalism
Rohit Kishan Ray, R. Srikanth, Sonjoy Majumder
Quantum walks play a crucial role in quantum algorithms and computational problems. Many-body quantum walks can reveal and exploit quantum correlations that are unavailable for sin…
On the distinction between distinguishability of states and witness of non-Markovianity of dynamical maps
Vijay Pathak, R. Srikanth
Non-P-divisibility is the strongest divisibility-based notion of quantum non-Markovianity. The generalized trace distance (GTD) based criterion is known to be an optimal witness of…
