Characterisation of polarisationentangled photon source for quantum key distribution.
(2016)Entanglement in real physical systems has been of great interest due to its importance in quantum mechanics. It has applications related to quantum information science speci cally quantum cryptography since it eliminates ... 
Determination of quantum entanglement concurrence using multilayer perceptron neural networks.
(2017)Artificial Neural Networks, inspired by biological neural networks, have seen widespread implementations across all research areas in the past few years. This partly due to recent developments in the field and mostly due ... 
Development of a postprocessing technique for a Quantum Key Distribution system.
(2017)Quantum Information, Processing and Communication (QIPC) is a field concerned with technological implementations established on quantum mechanical phenomena. It is established on the concept that the action of ... 
Devices for the construction of a cold atom experiment.
(2013)The experimental setup for laser cooling and trapping of 87Rb atoms with the aid of a Magnetooptical trap (MOT) is discussed. The experiment has a diverse setup, which includes: a vacuum system in which the cooling and ... 
Dynamics and thermalization of a fermion in a fermionic bath embedded in a bosonic bath.
(2013)We consider a model consisting of a finite number of quantum dots each of which confines a spinless electron. We zoom in on a single quantum dot containing an electron of interest treating it as being strongly coupled ... 
Experimental realization of quantum key distribution.
(2009)Nowadays, the information society that presides the everyday life is dependent on the communication industry to facilitate unintelligible data transfers between authenticated parties. Human desire to communicate ... 
Generalisation of theory and algorithms for the configurational temperature Nosé–Hoover thermostat.
(2015)In this dissertation we reformulate the configurational temperature Nos`eHoover thermostat proposed by Braga and Travis (C. Braga and K.P. Travis, 2005), using the antisymmetric matrix formalism found in (A. Sergi, ... 
The implementation of polarisation encoded quantum key distribution in fibre.
(2012)Quantum Key Distribution (QKD) employs the laws of quantum mechanics for the purpose of cryptography. Two parties, commonly called Alice and Bob, are able to share a random key which is used to encrypt a message. Any ... 
Monte Carlo simulations in open quantum systems.
(2007)The motivation for this Masters thesis is to develop numerical algorithms to study the dynamical evolution of nonMarkovian open quantum systems. Such systems are of importance if one is interested in modeling solid state ... 
Nonreversal open quantum walks.
(2015)In this thesis, a new model of nonreversal quantum walk is proposed. In such a walk, the walker cannot go back to previously visited sites but it can stay static or move to a new site. The process is set up on a line using ... 
Numerical simulations of fundamental lightmatter interactions.
(2017)We present the results of the numerical investigations of lightmatter interactions in one and two dimensions from the quantum mechanical perspective. We investigate the dynamics of twolevel systems coupled to quantized ... 
Quantum Key Distribution for the undergraduate curriculum.
(2017)Quantum Key Distribution (QKD) is one of the technological applications of quantum mechanics. The technology allows two users to securely establish an unbreakable key. The key is used to encrypt and decrypt sensitive ... 
Security and entanglement in differentialphaseshift quantum key distribution.
(2009)Quantum key distribution (QKD) aims at the creation of a secret key in the two locations of partners, traditionally Alice and Bob, wishing to communicate in private. A generic QKD protocol utilises a quantum channel and ... 
Simple qubit systems in bosonic baths.
(2010)The study is focused on the thermal entanglement of spin chains. Chains consisting of two and three qubits are considered. These chains are considered open because they are coupled to bosonic baths at different temperatures. ...
