Evaluation of entanglement measures by a single observable
Chengjie Zhang, Sixia Yu, Qing Chen +2
We present observable lower bounds for several bipartite entanglement measures including entanglement of formation, geometric measure of entanglement, concurrence, convex-roof exte…
Singularity of dynamical maps
S. C. Hou, X. X. Yi, S. X. Yu +1
For a dynamical map , which sends a state of quantum open system to a state , the decomposition law may break down at a sp…
Observable estimation of entanglement of formation and quantum discord for bipartite mixed quantum states
Chengjie Zhang, Sixia Yu, Qing Chen +1
We present observable lower and upper bounds for the entanglement of formation (EOF) and quantum discord (QD), which facilitates estimates of EOF and QD for arbitrary experimental…
An alternative non-Markovianity measure by divisibility of dynamical map
S. C. Hou, X. X. Yi, S. X. Yu +1
Identifying non-Markovianity with non-divisibility, we propose a measure for non-Markovinity of quantum process. Three examples are presented to illustrate the non-Markovianity, me…
Effective Hamiltonian Approach to Open Systems and Its Applications
X. L. Huang, X. X. Yi, Chunfeng Wu +3
By using the effective Hamiltonian approach, we present a self-consistent framework for the analysis of geometric phases and dynamically stable decoherence-free subspaces in open s…
