Convexity and non-Markovianity of Weyl Maps
Wen Xu, Vinayak Jagadish
We investigate the emergence of non-Markovian dynamics in finite-dimensional open quantum systems governed by Weyl dynamical maps and their convex combinations. Using the Hermite n…
Realizing the Petz Recovery Map on an NMR Quantum Processor
Gayatri Singh, Ram Sagar Sahani, Vinayak Jagadish +3
The Petz recovery map is a central construct in quantum information theory, providing an explicit, channel-aware prescription for reversing the effects of noise. Unlike standard qu…
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…
Eternal non-Markovianity of qubit maps
Vinayak Jagadish, R. Srikanth
As is well known, unital Pauli maps can be eternally non-CP-divisible. In contrast, here we show that in the case of non-unital maps, eternal non-Markovianity in the non-unital par…
Experimental realization of quantum non-Markovianity through the convex mixing of Pauli semigroups on an NMR quantum processor
Vaishali Gulati, Vinayak Jagadish, R. Srikanth +1
This experimental study aims to investigate the convex combinations of Pauli semigroups with arbitrary mixing parameters to determine whether the resulting dynamical map exhibits M…
Noninvertibility and non-Markovianity of quantum dynamical maps
Vinayak Jagadish, R. Srikanth, Francesco Petruccione
We identify two broad types of noninvertibilities in quantum dynamical maps, one necessarily associated with CP indivisibility and one not so. We study the production of (non-)Mark…
