Quantum information, Bell inequalities and the no-signalling principle
… bound on the success probability of a class of quantum teleportation protocols, denoted as port-based teleportation, from the no-cloning theorem and the no-signalling principle. Chapter 4 introduces the principle of quantum information causality. Chapter 2 considers the predictions of quantum …

A Quantum Light Source for Quantum Information Applications in the Telecom C-Band
Semiconductor quantum dot (QD) quantum light sources have long been established as suitable candidates for many quantum information applications, due to the on-demand emission of highly pure and highly indistinguishable single and entangled photons. A key factor in the development of this …

Telecom Wavelength Quantum Devices
Semiconductor quantum dots (QDs) are well established as sub-Poissonian sources of entangled photon pairs. To improve the utility of a QD light source, it would be advantageous to extend their emission further into the near infrared, into the low absorption wavelength windows utilised in long-haul …

Polarization Sensitive Imaging Techniques Using Quantum Entangled Qubits
… research is to study imaging techniques using quantum entangled qubits. These techniques extract information about the quantum state of two entangled qubits and corelate the degree of entanglement to each pixel. Imaging information of the underlying structure or material is decoded using the …

Comparison, optimization, and application of various spontaneous parametric downconversion sources of polarization-entangled photon pairs
As benchtop quantum information protocols become increasingly more advanced and the distances over which these experiments are performed become significantly longer, integrated optics provide a small, robust, and practical alternative to traditional bulk optics. Waveguide technology makes it …
