Negative refraction with low absorption using EIT in a four-level left-handed atomic system
Shun-Cai Zhao, Zheng-Dong Liu, Gen Li +1
We suggest a scheme for obtaining negative refraction with low absorption in a left-handed atomic system.Under the the appropriate conditions,the atomic system displays negative re…
Left handness in a four-level atomic system
Shuncai Zhao, Zhengdong Liu
A scheme is proposed for realizing simultaneous negative permittivity and negative permeability based on quantum coherence in a four-level dense atomic system here.Under some param…
Coherence dynamics in quantum algorithm for linear systems of equations
Linlin Ye, Zhaoqi Wu, Shao-Ming Fei
Quantum coherence is a fundamental issue in quantum mechanics and quantum information processing. We explore the coherence dynamics of the evolved states in HHL quantum algorithm f…
Tsallis relative entropy of coherence dynamics in Grover's search algorithm
Linlin Ye, Zhaoqi Wu, Shao-Ming Fei
Quantum coherence plays a central role in Grover's search algorithm. We study the Tsallis relative entropy of coherence dynamics of the evolved state in Grover's search algori…
Coherence and entanglement dynamics in Shor's algorithm
Linlin Ye, Zhaoqi Wu, Shao-Ming Fei
Shor's algorithm outperforms its classical counterpart in efficient prime factorization. We explore the coherence and entanglement dynamics of the evolved states within Shor's algo…
Quantifying magic via quantum Jensen-Shannon divergence
Linmao Wang, Zhaoqi Wu
Magic states play an important role in fault-tolerant quantum computation, and so the quantification of magic for quantum states is of great significance. In this work, we propose…
