Entangling single atoms over 33 km telecom fibre
Tim van Leent, Matthias Bock, Florian Fertig +10
Heralded entanglement between distant quantum memories is the key resource for quantum networks. Based on quantum repeater protocols, these networks will facilitate efficient large…
Experimental device-independent quantum key distribution between distant users
Wei Zhang, Tim van Leent, Kai Redeker +7
Device-independent quantum key distribution (DIQKD) is the art of using untrusted devices to establish secret keys over an untrusted channel. So far, the real-world implementation…
Long-distance distribution of atom-photon entanglement at telecom wavelength
Tim van Leent, Matthias Bock, Robert Garthoff +6
Entanglement between stationary quantum memories and photonic channels is the essential resource for future quantum networks. Together with entanglement distillation it will enable…
Unitary Transformation in Probabilistic Teleportation
Xiu-Lao Tian, Wei Zhang, Xiao-Qiang Xi
We proposed a general transformation in probabilistic teleportation, which is based on different entanglement matching coefficients corresponding to different unitary evolution…
Modified entanglement purification scheme with doubly entangled photon state
Chuan Wang, Yu-Bo Sheng, Xi-Han Li +3
Recently Xiao et al. proposed a scheme for entanglement purification based on doubly entangled photon states (Phys. Rev. A 77(2008) 042315). We modify their scheme for improving th…
Simulation of a Heisenberg XY- chain and realization of a perfect state transfer algorithm using liquid nuclear magnetic resonance
Jingfu Zhang, Gui Lu Long, Wei Zhang +3
The three- spin chain with Heisenberg XY- interaction is simulated in a three- qubit nuclear magnetic resonance (NMR) quantum computer. The evolution caused by the XY- interaction…
