Source attack decoy-state quantum key distribution phase information
2016/1/23
Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve information-theoretically secure key generation. This field is now approaching the stage of commercialization, but many...
A team of researchers from the University of California, Riverside, Bourns College of Engineering and the Russian Academy of Science has demonstrated a new type of holographic memory device that could...
Tunable subpicosecond electron bunch train generation using a transverse-to-longitudinal phase space exchange technique
Tunable subpicosecond electron bunch train generation transverse-to-longitudinal phase space
2010/11/16
We report on the experimental generation of a train of subpicosecond electron bunches. The bunch train generation is accomplished using a beamline capable of exchanging the coordinates between the hor...
Direct regular-to-chaotic tunneling rates using the fictitious integrable system approach
Direct regular-to-chaotic tunneling rates fictitious integrable system approach
2010/10/21
We review the fictitious integrable system approach which predicts dynamical tunneling rates
from regular states to the chaotic region in systems with a mixed phase space. It is based on the introduc...
Signal Enhancement and Background Suppression Using Interference and Entanglement
Signal Enhancement Background Suppression
2010/3/10
We describe a two-photon absorption process that is excited by entangled pairs but not non-entangled pairs with the same energy and polarization. Photon states can be selected so that in the non-entan...

2009/12/24
In this paper, we investigate the performance of a cylindrical positron emission mammography (PEM) by simulation, in order to estimate its feasibility before implementation. A well-developed simulatio...
Towards one machine, two purposes: using a common SC linac for XFEL and ERL simultaneously
electron linac XFEL ERL
2009/12/24
The linac based XFEL and ERL are advanced (or, say, 4th generation) light sources, with different electron beam parameters and different advantages. However, the linac used for XFEL and ERL should pro...
