Linear-Optical Implementation of Perfect Discrimination between Single-bit Unitary Operations
Pei Zhang, Liang Peng, Zhi-Wei Wang +4
Discrimination of unitary operations is a fundamental quantum information processing task. Assisted with linear optical elements, we experimentally demonstrate perfect discriminati…
Experimental entanglement verification and quantification via uncertainty relations
Zhi-Wei Wang, Yun-Feng Huang, Xi-Feng Ren +2
We report on experimental studies on entanglement quantification and verification based on uncertainty relations for systems consisting of two qubits. The new proposed measure is s…
Linear Optical Implemention of a Quantum Network for Quantum Estimation
Zhi-Wei Wang, Jian Li, Yun-Feng Huang +4
We present a scheme for simulating the quantum network of quantum estimation proposed by A. K. Ekert et al. [Phys. Rev. Lett. 88, 217901 (2002)]. We experimentally implement the sc…
Spatial mode properties of plasmon assisted transmission
Xi-Feng Ren, Guo-Ping Guo, Yun-Feng Huang +2
Orbital angular momentum of photons is explored to study the spatial mode properties of plasmon assisted transmission process. We found that photons carrying different orbital angu…
Experimental Entanglement Distillation of Two-qubit Mixed States Under Local filtering Operations
Zhi-Wei Wang, Xiang-Fa Zhou, Yun-Feng Huang +3
We experimentally demonstrate optimal entanglement distillation from two forms of two-qubit mixed states under local filtering operations according to the constructive method intru…
Manipulating quantum states with aspheric lenses
Zhi-Wei Wang, Xi-Feng Ren, Yun-Feng Huang +2
We present an experimental demonstration to manipulate the width and position of the down-converted beam waist. Our results can be used to engineer the two-photon orbital angular m…
