We study the dynamics of quantum-memory-assisted entropic uncertainty for a hybrid qutrit–qubit system interacting with fluctuating quantum scalar field in the background of expanding de Sitter space. We firstly derive the master equation that the system evolution obeys. As evolution time goes by, for different initial states, entropic uncertainty develops to different fixed values for different parameter values, whereas entanglement always decays to zero, and there exist monotonous relations…

Exploration of entropic uncertainty relation for two accelerating atoms immersed in a bath of electromagnetic field
TLDR
This paper studies the dynamics of quantum-memory-assisted entropic uncertainty relation for two accelerating atoms coupled with a bath of fluctuating electromagnetic field and finds that the mixedness is bound up with the entropics uncertainty.
Dynamics of entropic uncertainty for atoms immersed in thermal fluctuating massless scalar field
TLDR
The dynamics of quantum memory-assisted entropic uncertainty relation for two atoms immersed in a thermal bath of fluctuating massless scalar field is investigated and it is found that temperature can increase the uncertainty, but two-atom separation does not always increase the confidence.
Quantum-memory-assisted entropic uncertainty principle, teleportation, and entanglement witness in structured reservoirs
We relate the principle of quantum-memory-assisted entropic uncertainty to quantum teleportation and show geometrically that any two-qubit state which lowers the upper bound of this uncertainty
Quantum discord and classical correlation can tighten the uncertainty principle in the presence of quantum memory
Uncertainty relations capture the essence of the inevitable randomness associated with the outcomes of two incompatible quantum measurements. Recently, Berta et al. [Nature Phys. 6, 659 (2010)] have
The quantum entropic uncertainty relation and entanglement witness in the two-atom system coupling with the non-Markovian environments
The quantum entropic uncertainty relation and entanglement witness in the two-atom system coupling with the non-Markovian environments are studied using the time-convolutionless master-equation
Competition between quantum correlations in the quantum-memory-assisted entropic uncertainty relation
With the aid of a quantum memory, the uncertainty about the measurement outcomes of two incompatible observables of a quantum system can be reduced. We investigate this measurement uncertainty bound
Dynamics of quantum correlation and coherence in de Sitter universe
TLDR
The degradation, generation, revival and enhancement of quantum correlation and coherence for three cases of different initial states: zero correlation state, nonzero correlation separable state and maximally entangled state are discussed.
