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…
Non-Markovian to Markovian decay in structured environments with correlated disorder
Mariana O. Monteiro, Nadja K. Bernardes, Eugene M. Broni +2
Manipulating the dynamics of open quantum systems is a crucial requirement for large-scale quantum computers. Finding ways to overcome or extend decoherence times is a challenging…
Non-Markovianity in High-Dimensional Open Quantum Systems using Next-generation Multicore Optical Fibers
Santiago Rojas-Rojas, Daniel MartÃnez, Kei Sawada +5
With the advent of quantum technology, the interest in communication tasks assisted by quantum systems has increased both in academia and industry. Nonetheless, the transmission of…
Distillation of quantum non-Markovianity
Thiago Melo D. Azevedo, Cristhiano Duarte, Nadja K. Bernardes
Non-Markovianty of open quantum systems dynamics is a physically relevant property which is usually associated with the backflow of (quantum) information. Using this paradigmatic m…
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…
