Decoherence, Anti-Decoherence, and Fisher Information [PDF]
Entropy, 2021 In this work, we study quantum decoherence as reflected by the dynamics of a system that accounts for the interaction between matter and a given field. The process is described by an important information geometry tool: Fisher’s information measure (FIM).

Dynamics of decoherence in a noisy driven environment [PDF]
Scientific ReportsWe analyze the decoherence dynamics of a central spin coupled to a spin chain with a time-dependent noisy magnetic field, focusing on how noise influences the system’s decoherence.

Entropy, 2022 Quantum decoherence is crucial to understanding the emergence of the classical world from the underlying quantum reality. Decoherence dynamics are unitary, although they superselect a preferred eigenbasis.

On the effect of decoherence on quantum tunnelling
SN Applied Sciences, 2021 This work proposes a series of quantum experiments that can, at least in principle, allow for examining microscopic mechanisms associated with decoherence.

Decoherence-Induced Sudden Death of Entanglement and Bell Nonlocality
Photonics, 2022 Decoherence due to the unwanted interaction between a quantum system and environment leads to the degradation of quantum coherence. In particular, for an entangled state, decoherence makes a loss of entanglement and Bell nonlocality known as entanglement

Scientific Reports, 2021 We propose a photonic procedure using cross-Kerr nonlinearities (XKNLs) to encode single logical qubit information onto four-photon decoherence-free states.

Quantum control in open and periodically driven systems
Advances in Physics: X, 2021 Quantum technology resorts to efficient utilization of quantum resources to realize technique innovation. The systems are controlled such that their states follow the desired manners to realize different quantum protocols. However, the decoherence caused

Decoherence and Landauer’s principle in qubit-cavity quantum-field-theory interaction
European Physical Journal C: Particles and Fields, 2023 We consider quantum decoherence and Landauer’s principle in qubit-cavity quantum field theory (QFT) interaction, treating the qubit as the system and cavity QFT as the environment. In particular, we investigate the changes that occur in the system with a

Stabilizer codes for open quantum systems
Scientific Reports, 2023 The Lindblad master equation describes the evolution of a large variety of open quantum systems. An important property of some open quantum systems is the existence of decoherence-free subspaces.
