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…
An Optical-Infrared Study of the Young Multipolar Planetary Nebula NGC 6644
Chih-Hao Hsia, Sun Kwok, Yong Zhang +2
High-resolution HST imaging of the compact planetary nebula NGC 6644 has revealed two pairs of bipolar lobes and a central ring lying close to the plane of the sky. From mid-infrar…
Evaporative Cooling of Antiprotons to Cryogenic Temperatures
ALPHA Collaboration, G. B. Andresen, M. D. Ashkezari +37
We report the application of evaporative cooling to clouds of trapped antiprotons, resulting in plasmas with measured temperature as low as 9~K. We have modeled the evaporation pro…
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…
