Entangled Photon Pairs from Semiconductor Quantum Dots
N. Akopian, N. H. Lindner, E. Poem +5
Tomographic analysis demonstrates that the polarization state of pairs of photons emitted from a biexciton decay cascade becomes entangled when spectral filtering is applied. The m…
An artificial atom locked to natural atoms
N. Akopian, R. Trotta, E. Zallo +5
Single-photon sources that emit photons at the same energy play a key role in the emerging concepts of quantum information, such as entanglement swapping, quantum teleportation and…
Distilling entanglement from cascades with partial "Which Path" ambiguity
E. A. Meirom, N. H. Lindner, Y. Berlatzky +4
We develop a framework to calculate the density matrix of a pair of photons emitted in a decay cascade with partial "which path" ambiguity. We describe an appropriate entanglement…
Polarization sensitive spectroscopy of charged Quantum Dots
E. Poem, J. Shemesh, I. Marderfeld +6
We present an experimental and theoretical study of the polarized photoluminescence spectrum of single semiconductor quantum dots in various charge states. We compare our high reso…
Emission characteristics of quantum dots in planar microcavities
G. Ramon, U. Mizrahi, N. Akopian +5
The emission properties of single quantum dots in planar microcavities are studied experimentally and theoretically. Fivefold Enhanced spontaneous emission outside the microcavity…
A comment on "A semiconductor source of entangled photons"
N. H. Lindner, J. Avron, N. Akopian +1
When basic tools of quantum information are applied to the quantum tomography data presented in Nature 439, 179 (2006), none of their devices appears to be a source of entangled ph…
