Long-distance practical quantum key distribution by entanglement swapping
Artur Scherer, Barry C. Sanders, Wolfgang Tittel
We develop a model for practical, entanglement-based long-distance quantum key distribution employing entanglement swapping as a key building block. Relying only on existing off-th…
Addendum to "Single photon logic gates using minimum resources"
Qing Lin, Bing He
The authors call attention to a previous work [Qing Lin and Bing He, Phys. Rev. A 80, 042310 (2009)] on the realization of multi-qubit logic gates with controlled-path and merging…
Spatial search using the discrete time quantum walk
Neil B. Lovett, Matthew Everitt, Matthew Trevers +3
We study the quantum walk search algorithm of Shenvi, Kempe and Whaley [PRA 67 052307 (2003)] on data structures of one to two spatial dimensions, on which the algorithm is thought…
Quantum process tomography with coherent states
Saleh Rahimi-Keshari, Artur Scherer, Ady Mann +3
We develop an enhanced technique for characterizing quantum optical processes based on probing unknown quantum processes only with coherent states. Our method substantially improve…
Temporally multiplexed quantum repeaters with atomic gases
Christoph Simon, Hugues de Riedmatten, Mikael Afzelius
We propose a temporally multiplexed version of the Duan-Lukin-Cirac-Zoller (DLCZ) quantum repeater protocol using controlled inhomogeneous spin broadening in atomic gases. A first…
All Maximally Entangled Four Qubits States
Gilad Gour, Nolan R. Wallach
We find an operational interpretation for the 4-tangle as a type of residual entanglement, somewhat similar to the interpretation of the 3-tangle. Using this remarkable interpretat…
