In this chapter we review the use of semiconductor quantum dots as sources of quantum light. Principally, we focus on resonant two-photon excitation, which is a method that allows for on-demand generation of photon pairs. We explore the advantages of resonant excitation and present a number of results that were made in this excitation regime. In particular, we cover the following topics: photon statistics, coherent manipulation of the ground-excited state superposition, and generation of time…

Regulated and entangled photons from a single quantum Dot

It is proposed that this semiconductor device uses a single quantum dot as active medium embedded in a p- i- n junction and surrounded by a microcavity has the unique potential to generate pairs of entangled photons at a well-defined repetition rate.

Entangled photon pairs from semiconductor quantum dots.

Tomographic analysis demonstrates that the polarization state of pairs of photons emitted from a biexciton decay cascade becomes entangled when spectral filtering is applied and that the remanent information in the quantum dot degrees of freedom is negligible.

A quantum dot single-photon turnstile device.

Using pulsed laser excitation of a single quantum dot, a single- photon turnstile device that generates a train of single-photon pulses was demonstrated.

Creating polarization-entangled photon pairs from a semiconductor quantum dot using the optical Stark effect.

This work uses an external field, here a continuous-wave laser tuned to the QD in the ac Stark limit, to cancel the splitting and create two-photon entanglement, and shows that polarization-entangled photons can be routinely produced in semiconductor nanostructures.

Deterministic photon pairs and coherent optical control of a single quantum dot.

The biexciton binding energy is exploited to create an extremely clean single photon source via two-photon resonant excitation of an InAs/GaAs quantum dot and full coherent control of the ground-biexciton state qubit is performed and an extended coherence time is observed.

Improved fidelity of triggered entangled photons from single quantum dots

We demonstrate the triggered emission of polarization-entangled photon pairs from the biexciton cascade of a single InAs quantum dot embedded in a GaAs/AlAs planar microcavity. Improvements in the…

Fast radiative quantum dots: From single to multiple photon emission

Photon correlation measurements are performed on single GaAs quantum dots with various excitonic radiative lifetimes. A continuous increase of the probability that the quantum dot emits more than one…

Evolution of entanglement between distinguishable light states.

It is concluded that emission of photon pairs by a typical quantum dot with finite polarization splitting is in fact entangled in a time-evolving state, and not classically correlated as previously regarded.

Polarization entangled photons from quantum dots embedded in nanowires.

This Letter presents entanglement generated from a novel structure: a single InAsP quantum dot embedded in an InP nanowire, which can grow in a site-controlled way and exhibit high collection efficiency.

Efficiency vs. multi-photon contribution test for quantum dots.

Measurements show, that the light emitted from the quantum dot when it is resonantly excited possess a very low multi-photon content, and the non-Gaussian nature of the quantum state emitted from a single quantum dot is demonstrated.
