Optical Nondestructive Controlled-NOT Gate without Using Entangled Photons
Xiao-Hui Bao, Teng-Yun Chen, Qiang Zhang +4
We present and experimentally demonstrate a novel optical nondestructive controlled-NOT gate without using entangled ancilla. With much fewer measurements compared with quantum pro…
Non-local generation of entanglement of photons which do not meet each other
Juergen Roesch, Xian-Min Jing, Juan Yin +2
We report for the first time in an ancilla-free process a non-local entanglement between two single photons which do not meet. For our experiment we derive a simple and efficient m…
Experimental entanglement of six photons in graph states
Chao-Yang Lu, Xiao-Qi Zhou, Otfried Gühne +6
Graph states are special kinds of multipartite entangled states that correspond to mathematical graphs where the vertices take the role of quantum spin systems and the edges repres…
Experimental Quantum Teleportation of a Two-Qubit Composite System
Qiang Zhang, Alexander Goebel, Claudia Wagenknecht +6
Quantum teleportation, a way to transfer the state of a quantum system from one location to another, is central to quantum communication and plays an important role in a number of…
Simple protocol for secure decoy-state quantum key distribution with a loosely controlled source
Xiang-Bin Wang, Cheng-Zhi Peng, Jian-Wei Pan
The method of decoy-state quantum key distribution (QKD) requests different intensities of light pulses. Existing theory has assumed exact control of intensities. Here we propose a…
Collisional decoherence during writing and reading quantum states
Stephanie Manz, Thomas Fernholz, Joerg Schmiedmayer +1
Collisions, even though they do not limit the lifetime of quantum information stored in ground state hyperfine coherences, may severely limit the fidelity for quantum memory when t…
