Network Integration of a Quantum Dot Entangled Photon-pair Source
Sub-Poissonian entangled photon-pair sources based on semiconductor quantum dots are promising devices for the construction of a secure quantum network, thanks to their natural lack of multi photon-pair generation. In the previous decades, we have witnessed the achievements on a large variety of …

Analysis of a Deterministic Entangled Photon Pair Source using Single Photons
… involve the use of deterministic entangled photon pair sources. On the other hand heralded entangled photon pair sources have been proposed independently both with parametric down conversion source and single photon sources. We modify the latter scheme to implement it as an on demand …

High performance photon-pair source based on a fiber-coupled periodically poled KTiOPO₄ waveguide
Photon-pair sources based on spontaneous parametric downconversion (SPDC) in a nonlinear crystal waveguide have been shown to be significantly more efficient than those in a bulk crystal. To utilize waveguide sources in quantum information processing (QIP) applications, it is highly desirable to …

CORRELATED PHOTON PAIRS AND MULTIPHOTON STATES FROM A COLD ATOMIC ENSEMBLE
Narrowband correlated photon pairs are vital for interfacing neutral atom systems and realizing distributed quantum networks. This thesis presents the realization and characterization of a high-brightness, temporally correlated photon-pair source at near-resonant wavelengths of 780 nm and 795 nm in …

Applications of single-photon two-qubit quantum logic to the quantum information science
… information processing tasks using single-photon two-qubit (SPTQ) quantum logic. As an initial state of those tasks, I used various entangled photon pairs, and I describe development of a polarization entangled photon pair source based on a collinear spontaneous parametric down conversion …

Quantum applications of Raman-mediated photon-pair generation
Controllable generation of photon pairs is essential for the utilization of quantum pair states for quantum applications such as quantum communication, quantum cryptography, teleportation, and linear optics quantum computing. Raman scattering is one of the most fundamental light-matter interactions …

Development of 1GHz Clocked Entangled LEDs for Fibre Networks
… quantum dots (QD)s have been well established as sources of single photons and entangled photon-pairs, both of which are essential for realising quantum networks. To be compatible with real-world applications, such a source must further conform to basic requirements including operation at telecom …
