Disclosing the spatio-temporal structure of PDC entanglement through frequency up-conversion
spatio-temporal structure of PDC entanglement frequency up-conversion Optics
2012/5/29
In this work we propose and analyse a scheme where the full spatio-temporal correlation of twin photons/beams generated by parametric down-conversion is detected by using its inverse process, i.e. sum...
Entanglement of light-shift compensated atomic spin waves with telecom light
Entanglement light-shift compensated atomic spin waves telecom light
2010/10/20
Entanglement of a 795 nm light polarization qubit and an atomic Rb spin wave qubit for a storage time of 0.1 s is observed by measuring the violation of Bell’s inequality (S = 2.65±0.12). Long qubit s...

Qubit Entanglement Dephasing Dynamics Driven Bath of Spins
2010/10/19
We study the entanglement dynamics for a two-spin system coupled to a spin environment of
different configurations by z-x type interaction. The models considered in this paper are solved both analyti...
Entanglement spectrum of random-singlet quantum critical points
Entanglement spectrum random-singlet quantum critical points
2010/10/22
The entanglement spectrum, i.e., the full distribution of Schmidt eigenvalues of the reduced
density matrix, contains more information than the conventional entanglement entropy and has been studied ...
Entanglement and nonclassicality for multi-mode radiation field states
Entanglement nonclassicality multi-mode radiation field states
2010/10/21
Nonclassicality in the sense of quantum optics is a prerequisite for entanglement in multi-mode
radiation states. In this work we bring out the possibilities of passing from the former to the
latter...
Distillation of mixed-state continuous-variable entanglement by photon subtraction
Distillation mixed-state continuous-variable entanglement photon subtraction
2010/10/21
We present a detailed theoretical analysis for the distillation of one copy of a mixed two-mode
continuous-variable entangled state using beamsplitters and coherent photon-detection techniques,includ...
Quantum State Generation and Entanglement Manipulation Using Linear Optics
linear optics quantum state entanglement manipulation
2010/4/12
Quantum information processing (QIP) requires unitary operations, measurements and synthesis, manipulation and characterization of arbitrary quantum states. Linear optics provides efficient tools for ...
Limitations on the Creation of Maximal Entanglement
Limitations Creation Maximal Entanglement
2010/10/15
We study a limited set of optical circuits for creating near maximal polarisation entanglement
without the usual large vacuum contribution. The optical circuits we consider involve passive interferom...
