Supersensitivity of Kerr phase estimation with two-mode squeezed vacuum states
Yun-Feng Guo, Wei Zhong, Lan Zhou +1
We analytically investigate the sensitivity of Kerr nonlinear phase estimation in a Mach-Zehnder interferometer with two-mode squeezed vacuum states. We find that such a metrologic…
Experimental one-step deterministic entanglement purification
Cen-Xiao Huang, Xiao-Min Hu1, Bi-Heng Liu +4
Entanglement purification is to distill high-quality entangled states from low-quality entangled states. It is a key step in quantum repeaters, determines the efficiency and commun…
Few-photon optical diode in a chiral waveguide
Jin-Lei Tan, Xun-Wei Xu, Jing Lu +1
We study the coherent transport of one or two photons in a 1D waveguide chirally coupled to a nonlinear resonator. Analytic solutions of the one-photon and two-photon scattering is…
High-efficient two-step entanglement purification using hyperentanglement
Lan Zhou, Yu-Bo Sheng
Entanglement purification is a powerful method to distill the high-quality entanglement from low-quality entanglement. In the paper, we propose an efficient two-step entanglement p…
High efficient multipartite entanglement purification using hyperentanglement
Lan Zhou, Pei-Shun Yan, Wei Zhong +1
Multipartite entanglement plays an important role in controlled quantum teleportation, quantum secret sharing, quantum metrology and some other important quantum information branch…
Long-distance entanglement purification for quantum communication
Xiao-Min Hu, Cen-Xiao Huang, Yu-Bo Sheng +8
High-quality long-distance entanglement is essential for both quantum communication and scalable quantum networks. Entanglement purification is to distill high-quality entanglement…
