Bright source of spectrally pure polarization-entangled photons with nearly single-mode emission
Bright source spectrally polarization-entangled photons nearly single-mode emission
2010/10/19
We present results of a bright entangled photon source operating at 1552 nm via type-II collinear degenerate spontaneous parametric down-conversion in periodically poled KTP crystal. We report a conse...
Largest Schmidt eigenvalue of entangled random pure states and conductance distribution in chaotic cavities
Largest Schmidt eigenvalue entangled random pure states conductance distribution chaotic cavities
2010/10/21
A strategy to evaluate the distribution of the largest Schmidt eigenvalue for entangled random pure states of bipartite systems is proposed. We point out that the multiple integral defining the sought...
Svetlichny's inequality and genuine tripartite nonlocality in three-qubit pure states
Svetlichny's inequality genuine tripartite nonlocality three-qubit pure states
2010/4/7
The violation of the Svetlichny's inequality (SI) [Phys. Rev. D, 35, 3066 (1987)] is sufficient but not necessary for genuine tripartite nonlocal correlations. Here we quantify the relationship betwee...
Pure single photon generation by type-I PDC with backward-wave amplification
Pure single photon type-I PDC backward-wave amplification
2010/4/8
We explore a promising method of generating pure heralded single photons. Our approach is based on parametric downconversion in a periodically-poled waveguide. However, unlike conventional downconvers...
An Experimentally accessible geometric measure for entanglement in $N$-qudit pure states
An Experimentally accessible geometric entanglement $N$-qudit pure states
2010/4/8
We present a multipartite entanglement measure for $N$-qudit pure states, using the norm of the correlation tensor which occurs in the Bloch representation of the state. We compute this measure for im...
