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…
