Bell-Mermin-Klyshko Inequalities and One-way Information Deficit of Dirac Fields in Noninertial Frames
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
We investigate the Bell-Mermin-Klyshko inequalities and the one-way information deficit of Dirac fields in noninertial frames, where the quantum correlations are shared between ine…
Dynamics of quantum battery capacity under Markovian channels
Yao-Kun Wang, Li-Zhu Ge, Tinggui Zhang +2
We study the dynamics of the quantum battery capacity for the Bell-diagonal states under Markovian channels on the first subsystem. We show that the capacity increases for special…
Steered quantum coherence and quantum Fisher information in spin-chain system
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
In this paper, we investigate steered quantum coherence, i.e., the norm of steered coherence and the relative entropy of steered coherence, and the quantum Fisher information…
One-Way Deficit and Holevo Quantity of Generalized -qubit Werner State
Yao-Kun Wang, Rui-Xin Chen, Li-Zhu Ge +2
Originated from the work extraction in quantum systems coupled to a heat bath, quantum deficit is a kind of significant quantum correlations like quantum entanglement. It links qua…
A Note on Holevo quantity of -invariant states
Yao-Kun Wang, Li-Zhu Ge, Shao-Ming Fei +1
The Holevo quantity and the -invariant states have particular importance in quantum information processing. We calculate analytically the Holevo quantity for bipartite syste…
Quantum coherence in mutually unbiased bases
Yao-Kun Wang, Li-Zhu Ge, Yuan-Hong Tao
We investigate the norm of coherence of quantum states in mutually unbiased bases. We find that the sum of squared norm of coherence of the mixed state single qubit…
The Geometry of Quantum Coherence for Two Qubit States
Yao-Kun Wang, Lian-He Shao, Yu-Ran Zhang
We plot the geometry of several distance-based quantifiers of coherence for Bell-diagonal states. We find that along with both norm and relative entropy of coherence change…
One-way Quantum Deficit and Decoherence for Two-qubit States
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
We study one-way quantum deficit of two-qubit states systematically from analytical derivations. An effective approach to compute one-way quantum deficit of two-qubit state…
Comment on "One-way deficit of two qubit X states"
Naihuan Jing, Xia Zhang, Yao-Kun Wang
We improve the recent method of Wang et. al to calculate exactly the one-way information deficit of any X-state. Analytical formulas of the one-way information deficit are given fo…
Super quantum discord for X-type states
Tao Li, Teng Ma, Yaokun Wang +2
Weak measurement is a new way to manipulate and control quantum systems. Different from projection measurement, weak measurement only makes a small change in status. Applying weak…
Maximal Holevo quantity based on weak measurements
Yao-Kun Wang, Shao-Ming Fei, Zhi-Xi Wang +2
The Holevo bound is a keystone in many applications of quantum information theory. We propose "weak maximal Holevo quantity" with weak measurements as the generalization of the sta…
One-Way Deficit of Two Qubit X States
Yao-Kun Wang, Naihuan Jing, Shao-Ming Fei +3
Quantum deficit originates in questions regarding work extraction from quantum systems coupled to a heat bath [Phys. Rev. Lett. 89, 180402 (2002)]. It links quantum correlations wi…
Non-commutativity and Local Indistinguishability of Quantum States
Teng Ma, Ming-Jing Zhao, Yao-Kun Wang +1
We study the local indistinguishability problem of quantum states. By introducing an easily calculated quantity, non-commutativity, we present an criterion which is both necessary…
One-way deficit of SU(2) invariant states
Yao-Kun Wang, Teng Ma, Shao-Ming Fei +1
We calculate analytically the one-way deficit for systems consisting spin- and spin- subsystems with SU(2) symmetry. Comparing our results with the quantum discord of SU…
Super-quantum correlation and geometry for Bell-diagonal states with weak measurements
Yao-Kun Wang, Teng Ma, Heng Fan +2
We propose "super one-way deficit" by weak measurement as the generalization of one-way deficit defined for standard projective measurement. The super one-way deficit for Werner st…
The One-Way Information Deficit and Geometry for a Class of Two-qubit States
Yao-Kun Wang, Teng Ma, Bo Li +1
The work deficit, as introduced by Jonathan Oppenheim \emph{et al}[Phys. Rev. Lett. \textbf{89}, 180402 (2002)] is a good measure of the quantum correlations in a state and provide…
