Characterization of quantum and classical correlations in the Earth curved space-time
Tonghua Liu, Shuo Cao, Shumin Wu
The preparation of quantum systems and the execution of quantum information tasks between distant users are always affected by gravitational and relativistic effects. In this work,…
Quantum fluctuation of entanglement for accelerated two-level detectors
Sixuan Zhang, Tonghua Liu, Shuo Cao +3
Quantum entanglement as the one of the most general quantum resources, can be quantified by von Neumann entropy. However, as we know, the von Neumann entropy is only statistical qu…
Synchronization and estimation of gravity-induced time difference for quantum clocks
Jieci Wang, Tonghua Liu, Jiliang Jing +1
It has recently been reported [\textit{PNAS} \textbf{114}, 2303 (2017)] that, under an operational definition of time, quantum clocks would get entangled through gravitational effe…
The influence of the Earth's curved spacetime on Gaussian quantum coherence
Tonghua Liu, Shumin Wu, Shuo Cao
Light wave-packets propagating from the Earth to satellites will be deformed by the curved background spacetime of the Earth, thus influencing the quantum state of light. We show t…
Satellite-based quantum steering under the influence of spacetime curvature of the Earth
Tonghua Liu, Jiliang Jing, Jieci Wang
Spacetime curvature of the Earth deforms wavepackets of photons sent from the Earth to satellites, thus influencing the quantum state of light. We show that Gaussian steering of ph…
