Measure of set imaginarity
Yu Guo, Jiabo Pan, Yuqin Wang +1
Recent studies have shown that Bargmann invariants provide effective detectors of set imaginarity. In this paper, we investigate set imaginarity as a quantum resource in qubit syst…
Computable lower bound of the parameterized entanglement monotone
Ning Yang, Yu Guo, Shuanping Du
Although numerous measures of entanglement have been proposed so far, the calculation of a given faithful entanglement measure is a hard work since it is always involved in some op…
Unified entropy entanglement
Wenxue Ren, Binghao Li, Ruiqun Niu +2
The unified entropy as a promotion of the von Neumann entropy exhibits distinct diversity which contains the Tsallis entropy, the Rényi entropy, the von Neumann entropy as special…
Features of preparable entangled states in Gaussian quantum networks
Shuanping Du, Zhaofang Bai
Large-scale quantum networks have been employed to overcome practical constraints on transmission and storage for single entangled systems. The deterministic preparation of entangl…
Measure-independent description of wave-particle duality via coherence
Zhaofang Bai, ShuanpingDu
Wave-particle duality as one of the expression of Bohr complementarity is a significant concept in the field of quantum mechanics. Quantitative analysis of wave-particle duality ai…
Quantifying imaginarity in terms of pure-state imaginarity
Shuanping Du, Zhaofang Bai
Complex numbers are widely used in quantum physics and are indispensable components for describing quantum systems and their dynamical behavior. The resource theory of imaginarity…
State convertibility under genuinely incoherent operations
Zhaofang Bai, Shuanping Du
State convertibility is fundamental in the study of resource theory of quantum coherence. It is aimed at identifying when it is possible to convert a given coherent state to anothe…
Network mechanism for generating genuinely correlative Gaussian states
Zhaofang Bai, Shuanping Du
Generating a long-distance quantum state with genuine quantum correlation (GQC) is one of the most essential functions of quantum networks to support quantum communication. Here, w…
Frozen condition of quantum coherence
Zhaofang Bai, Shuanping Du
Quantum coherence as an important physical resource plays the key role in implementing various quantum tasks, whereas quantum coherence is often deteriorated due to the noise. In t…
Incoherent Gaussian equivalence of mode Gaussian states
Shuanping Du, Zhaofang Bai
Necessary and sufficient conditions for arbitrary multimode (pure or mixed) Gaussian states to be equivalent under incoherent Gaussian operations are derived. We show that two Gaus…
Conversion of Gaussian states under incoherent Gaussian operations
Shuanping Du, Zhaofang Bai
The coherence resource theory needs to study the operational value and efficiency which can be broadly formulated as the question: when can one coherent state be converted into ano…
Strictly incoherent operations for one-qubit systems
Shuanping Du, Zhaofang Bai
Strictly incoherent operations (SIO) proposed in [Phys. Rev. Lett. 116, 120404 (2016)] are promising to be a good candidate of free operations in the resource theory of quantum coh…
Coherent preorder of quantum states
Zhaofang Bai, Shuanping Du
As an important quantum resource, quantum coherence play key role in quantum information processing. It is often concerned with manipulation of families of quantum states rather th…

Xiaofei Qi, Zhaofang Bai, Shuanping Du
In this paper, by providing a class of coherence measures in finite dimensional systems, a sufficient and necessary condition for the existence of coherence transformations that co…
The Wigner-Yanase information can increase under phase sensitive incoherent operations
Shuanping Du, Zhaofang Bai
We found that the Wigner-Yanase skew information, which has been recently proposed as a measure of coherence in [Phys. Rev. Lett. \textbf{113}, 170401(2014)], can increase under a…
Coherence measures and optimal conversion for coherent states
Shuanping Du, Zhaofang Bai, Xiaofei Qi
We discuss a general strategy to construct coherence measures. One can build an important class of coherence measures which cover the relative entropy measure for pure states, the…

An entangled basis with fixed Schmidt number (EBk) is a set of orthonormal basis states with the same Schmidt number in a product Hilbert space $\mathbb{C}^d\otimes\mathbb{…
When quantum channel preserves product states
