Detecting metrologically useful asymmetry and entanglement by a few local measurements
Chao Zhang, Benjamin Yadin, Zhi-Bo Hou +8
Important properties of a quantum system are not directly measurable, but they can be disclosed by how fast the system changes under controlled perturbations. In particular, asymme…
Experimental generation of a high-fidelity four-photon linear cluster state
Chao Zhang, Yun-Feng Huang, Bi-Heng Liu +2
Cluster state plays a crucial role in the one-way quantum computation. Here, we propose and experimentally demonstrate a new scheme to prepare an ultrahigh-fidelity four-photon lin…
Time-invariant entanglement and sudden death of non-locality
Bi-Heng Liu, Xiao-Min Hu, Jiang-Shan Chen +8
We investigate both theoretically and experimentally the dynamics of entanglement and non-locality for two qubits immersed in a global pure dephasing environment. We demonstrate th…
