Metric space approach to potentials and its relevance to density functional theory
P. M. Sharp, I. D'Amico
External potentials play a crucial role in modelling quantum systems, since, for a given inter- particle interaction, they define the system Hamiltonian. We use the metric space ap…
Knitting distributed cluster state ladders with spin chains
R. Ronke, I. D'Amico, T. P. Spiller
There has been much recent study on the application of spin chains to quantum state transfer and communication. Here we discuss the utilisation of spin chains (set up for perfect q…
Quantum mechanics in metric space: wave functions and their densities
I. D'Amico, J. P. Coe, V. V. Franca +1
Hilbert space combines the properties of two fundamentally different types of mathematical spaces: vector space and metric space. While the vector-space aspects of Hilbert space, s…
Effect of perturbations on information transfer in spin chains
R. Ronke, T. P. Spiller, I. D'Amico
Spin chains have been proposed as a reliable and convenient way of transferring information and entanglement in a quantum computational context. Nonetheless, it has to be expected…
Geometry induced entanglement transitions in nanostructures
J. P. Coe, S. Abdullah, I. D'Amico
We model quantum dot nanostructures using a one-dimensional system of two interacting electrons. We show that strong and rapid variations may be induced in the spatial entanglement…
Effect of confinement potential geometry on entanglement in quantum dot-based nanostructures
S. Abdullah, J. P. Coe, I. D'Amico
We calculate the spatial entanglement between two electrons trapped in a nanostructure for a broad class of confinement potentials, including single and double quantum dots, and co…
