Pillar microcavities with an elliptical cross section have non degenerate linearly polarised fundamental cavity modes. Single photon emission from exciton doublets in InAs quantum dots embedded in the microcavity is also linearly polarised. By changing the sample temperature we are able to tune...

Temporal and polarization correlations between single photons emitted from different excitonic states confined in the same CdTe/ZnTe quantum dot (QD) were measured. Experiment was carried out at low temperature (T = 1.7 K) with nonresonant excitation and in an external magnetic field ranging...

We present a site-controlled, highly symmetric quantum dot system with a density of at least 15 % of polarization-entangled photon emitters. Fidelity values of the entangled state as high as 0.721Â±0.043 were found.

For circular quantum dot (QD), taking into account the Razhba spinâ€“orbit interaction (SOI), an exact energy spectrum is obtained. For a small SOI constant, the eigenfunctions of the QD are found. It is shown that the application of a radiation field with circular polarization removes the...

The article discusses a study by K. De Greve and W. B. Gao and colleagues which investigates the effect of quantum entanglement between a photon and a stationary particle. De Greve and colleagues found that electron's spin entangles with the polarization and colour of the photon. Moreover, Gao...

It is shown that the spin orientation and polarization of an exciton confined in a QD can be controlled via two-photon transitions, by virtually coupling the single-exciton states to the detuned ground and biexciton states. Furthermore, phonon-induced dephasing leading to loss of fidelity in the...

We study the multiexciton properties of GaAs quantum dots self aggregated on Si substrates. Sequential emission of two photons radiative cascade is observed both in continuous wave and in time resolved measurements. Polarization resolved measurements, with high spectral resolution, allow us to...

We theoretically analyze the yield and fidelity of the quantum state transfer (QST) from a photon polarization qubit to an electron spin qubit using a spin-coherent photo-detector consisting of a semiconductor quantum dot. We use the modified one-dimensional light-atom interaction model which...

Using three-photon polarization-entangled GHZ states or W states, we propose controlled quantum key distribution protocols for circumventing two main types of collective noise, collective dephasing noise, or collective rotation noise. Irrespective of the number of controllers, a three-photon...
