Security evaluation of quantum key distribution with weak basis-choice flaws
Shi-Hai Sun, Zhi-Yu Tian, Mei-Sheng Zhao +1
Quantum key distribution (QKD) can share an unconditional secure key between two remote parties, but the deviation between theory and practice will break the security of the genera…
Quantum Image Processing and Its Application to Edge Detection: Theory and Experiment
Xi-Wei Yao, Hengyan Wang, Zeyang Liao +12
Processing of digital images is continuously gaining in volume and relevance, with concomitant demands on data storage, transmission and processing power. Encoding the image inform…
Comment on "Quantitative Condition is Necessary in Guaranteeing the Validity of the Adiabatic Approximation" [arXiv:1004.3100]
Meisheng Zhao, Jianda Wu
Recently, the authors of Ref.1[arXiv:1004.3100] claimed that they have proven the traditional adiabatic condition is a necessary condition. Here, it is claimed that there are some…
Adiabatic Condition and Quantum Geometric Potential
Jianda Wu, Meisheng Zhao, Jianlan Chen +1
In this paper, we present a U(1)-invariant expansion theory of the adiabatic process. As its application, we propose and discuss new sufficient adiabatic approximation conditions.…
Graphical Nonbinary Quantum Error-Correcting Codes
Dan Hu, Weidong Tang, Meisheng Zhao +3
In this paper, based on the nonbinary graph state, we present a systematic way of constructing good non-binary quantum codes, both additive and nonadditive, for systems with intege…
Is the quantum adiabatic theorem consistent?
Jiangfeng Du, Lingzhi Hu, Ya Wang +3
The quantum adiabatic theorem states that if a quantum system starts in an eigenstate of the Hamiltonian, and this Hamiltonian varies sufficiently slowly, the system stays in this…
