Testing the Transverse Scalar Mode of Gravitational Quantum Field Theory with Taiji and LISA
Cong Xu, Yong Tang, Yue-Liang Wu
The paper investigates how the transverse scalar (breathing) polarization predicted by Gravitational Quantum Field Theory can be detected with space‑based gravitational‑wave detect…
Probing Gravitational Quantum Field Theory through Polarization Fingerprints of Gravitational Waves
Cong Xu, Hong-Bo Jin, Yue-Liang Wu
Gravitational Quantum Field Theory (GQFT) has been proposed as a candidate framework to reconcile general relativity with quantum field theory, and a distinctive imprint on gravita…
Quantum average correlations and complementarity relations via metric-adjusted skew information
Xiaoyu Ma, Qing-Hua Zhang, Cong Xu
We investigate quantum average correlations and complementarity relations based on metric-adjusted skew information. Several natural averaging procedures are considered, including…
Quantum average correlation based on average coherence
Xiaoyu Ma, Qing-Hua Zhang, Cong Xu
This paper studies the quantification and structural properties of quantum average correlation based on average coherence. Motivated by two mathematically equivalent approaches to…
Tighter entropic uncertainty relations in the presence of quantum memories for complete sets of mutually unbiased bases
Qing-Hua Zhang, Cong Xu, Jing-Feng Wu +1
Entropic uncertainty relations provide an information-theoretic framework for quantifying the fundamental indeterminacy inherent in quantum mechanics. We propose more stringent qua…
Quantifying nonclassical correlations relative to local channels
Cong Xu, Tao Li, Ruonan Ren +2
Nonclassical correlations are significant physical resources with extensive applications in quantum information processing. We introduce the modified Wigner-Yanase-Dyson skew infor…
