Generality of the concatenated five-qubit code
Long Huang, Bo You, Xiaohua Wu +1
In this work, a quantum error correction (QEC) procedure with the concatenated five-qubit code is used to construct a near-perfect effective qubit channel (with a error below $10^{…
Quantum discord for the general two-qubit case
Xiaohua Wu, Tao Zhou
Recently, Girolami and Adesso have demonstrated that the calculation of quantum discord for two-qubit case can be viewed as to solve a pair of transcendental equation (Phys. Rev. A…
Does the Berry phase in a quantum optical system originate from the rotating wave approximation
Minghao Wang, L. F. Wei, J. Q. Liang
The Berry phase (BP) in a quantized light field demonstrated more than a decade ago (Phys. Rev. Lett. 89, 220404) has attracted considerable attentions, since it plays an important…
Geometric discord: A resource for increments of quantum key distribution through twirling
Xiaohua Wu, Tao Zhou
In the present work, we consider a scenario where an arbitrary two-qubit pure state is applied to generate a randomly distributed key via the generalized EPR protocol. Using the tw…
