A pure Dirac's canonical analysis for four-dimensional BF theories
pure Dirac's canonical analysis four-dimensional BF theories Mathematical Physics
2011/9/19
Abstract: We perform Dirac's canonical analysis for a four-dimensional $BF$ and for a generalized four-dimensional $BF$ theory depending on a connection valued in the Lie algebra of SO(3,1). This anal...
A New Proposal for the Picture Changing Operators in the Minimal Pure Spinor Formalism
New Proposal the Minimal Pure Spinor Formalism High Energy Physics - Theory
2011/7/27
Abstract: Using a new proposal for the "picture lowering" operators, we compute the tree level scattering amplitude in the minimal pure spinor formalism by performing the integration over the pure spi...
Linearly independent pure-state decomposition and quantum state discrimination
Linearly independent decomposition quantum discrimination
2010/11/8
We put the pure-state decomposition mathematical property of a mixed state to a physical test. We begin by characterizing all the possible decompositions of a rank-two mixed state by means of the comp...
Connections of geometric measure of entanglement of pure symmetric states to quantum state estimation
Connections geometric measure entanglement pure symmetric states quantum state estimation
2010/11/5
We study the geometric measure of entanglement (GM) of pure symmetric states related to rank-one positive-operator-valued measures (POVMs) and establish a general connection with quantum state estimat...
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...
Local unitary equivalence and distinguishability of arbitrary multipartite pure states
Local unitary equivalence distinguishability arbitrary multipartite pure states
2010/10/18
Entanglement in multipartite quantum systems, due to its importance in quantum information theory, became a topic of numerous investigations (see [1] for a recent comprehensive
review of various aspe...
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...
