Reply to 'Comment on "Ideal clocks -- a convenient fiction"'
Krzysztof Lorek, Jorma Louko, Andrzej Dragan
For a quantum scalar field that is confined in a uniformly linearly accelerated cavity in Minkowski spacetime and interacts linearly with a scalar field that is not confined in the…
Effects of uniform acceleration on quantum states and vacuum entanglement in relativistic quantum information
Krzysztof Lorek
In this thesis we focus on the influence of uniform acceleration on quantum states and their properties, as well as on quantum entanglement contained in the vacuum. First, we analy…
Two-mode Gaussian quantum states measured by collinearly and noncollinearly accelerating observers
Piotr T. Grochowski, Krzysztof Lorek, Andrzej Dragan
We generalize -dimensional formalism derived by Ahmadi et. al. [Phys. Rev. D \textbf{93}, 124031] to investigate an effect of relativistic acceleration on localized two-mode G…
Effect of acceleration on localized fermionic Gaussian states: from vacuum entanglement to maximally entangled states
Benedikt Richter, Krzysztof Lorek, Andrzej Dragan +1
We study the effects of acceleration on fermionic Gaussian states of localized modes of a Dirac field. We consider two wave-packets in a Gaussian state and transform these to an ac…
Effect of relativistic motion on witnessing non-classicality of quantum states
Agata Chęcińska, Krzysztof Lorek, Andrzej Dragan
We show that the operational definition of non-classicality of a quantum state depends on the motion of the observer. We use the relativistic Unruh-DeWitt detector model to witness…
Effect of relativistic acceleration on localized two-mode Gaussian quantum states
Mehdi Ahmadi, Krzysztof Lorek, Agata Chęcińska +3
We study how an arbitrary Gaussian state of two localized wave packets, prepared in an inertial frame of reference, is described by a pair of uniformly accelerated observers. We ex…
Ideal clocks - a convenient fiction
Krzysztof Lorek, Jorma Louko, Andrzej Dragan
We show that no device built according to the rules of quantum field theory can measure proper time along its path. Highly accelerated quantum clocks experience the Unruh effect, w…
Extraction of genuine tripartite entanglement from the vacuum
Krzysztof Lorek, Daniel Pecak, Eric G. Brown +1
We demonstrate and characterize the extraction of genuine tripartite entanglement from the vacuum of a periodic cavity field. That is, three probe quantum systems (detectors) can b…
