Frozen and Invariant Quantum Discord under Local Dephasing Noise
Göktuğ Karpat, Carole Addis, Sabrina Maniscalco
In this chapter, we intend to explore and review some remarkable dynamical properties of quantum discord under various different open quantum system models. Specifically, our discu…
Dynamical Memory Effects in Correlated Quantum Channels
Carole Addis, Göktuğ Karpat, Chiara Macchiavello +1
Memory effects play a fundamental role in the study of the dynamics of open quantum systems. There exist two conceptually distinct notions of memory discussed for quantum channels…
The problem of coherent control in non-Markovian open quantum systems
Carole Addis, Elsi-Mari Laine, Clemens Gneiting +1
We critically evaluate the most widespread assumption in the theoretical description of coherent control strategies for open quantum systems. We show that, for non-Markovian open s…
Time-Invariant Discord in Dynamically Decoupled Systems
Carole Addis, Göktuğ Karpat, Sabrina Maniscalco
Dynamical decoupling protocols are one of the most used tools for efficient quantum error corrections and for reservoir engineering. In this paper we study the effect of dynamical…
Dynamics of incompatibility of quantum measurements in open systems
Carole Addis, Teiko Heinosaari, Jukka Kiukas +2
The non-classical nature of quantum states, often illustrated using entanglement measures or quantum discord, constitutes a resource for quantum information protocols. However, the…
Dynamical decoupling efficiency versus quantum non-Markovianity
Carole Addis, Francesco Ciccarello, Michele Cascio +2
We investigate the relationship between non-Markovianity and the effectiveness of a dynamical decoupling protocol for qubits undergoing pure dephasing. We consider an exact model i…
Comparative study of non-Markovianity measures in exactly solvable one and two qubit models
C. Addis, B. Bylicka, D. Chruściński +1
In this paper we present a detailed critical study of several recently proposed non-Markovianity measures. We analyse their properties for single qubit and two-qubit systems in bot…
Coherence trapping and information back-flow in dephasing qubits
Carole Addis, Gregoire Brebner, Pinja Haikka +1
We study the interplay between coherence trapping, information back-flow and the form of the reservoir spectral density for dephasing qubits. We show that stationary coherence is m…
