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…
Petz recovery maps for qudit quantum channels
Lea Lautenbacher, Vinayak Jagadish, Francesco Petruccione +1
This study delves into the efficacy of the Petz recovery map within the context of two paradigmatic quantum channels: dephasing and amplitude-damping. While prior investigations ha…
Approximating Invertible Maps by Recovery Channels: Optimality and an Application to Non-Markovian Dynamics
Lea Lautenbacher, Fernando de Melo, Nadja K. Bernardes
We investigate the problem of reversing quantum dynamics, specifically via optimal Petz recovery maps. We focus on typical decoherence channels, such as dephasing, depolarizing and…
