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…
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…
