Generalized Phase-Space Techniques to Explore Quantum Phase Transitions in Critical Quantum Spin Systems
N. M. Millen, R. P. Rundle, J. H. Samson +3
We apply the generalized Wigner function formalism to detect and characterize a range of quantum phase transitions in several cyclic, finite-length, spin- one-dimensio…
On quantum invariants and the graph isomorphism problem
P. W. Mills, R. P. Rundle, J. H. Samson +4
Three new graph invariants are introduced which may be measured from a quantum graph state and form examples of a framework under which other graph invariants can be constructed. E…
A general approach to quantum mechanics as a statistical theory
R. P. Rundle, Todd Tilma, J. H. Samson +3
Since the very early days of quantum theory there have been numerous attempts to interpret quantum mechanics as a statistical theory. This is equivalent to describing quantum state…
Quantum phase space measurement and entanglement validation made easy
R. P. Rundle, P. W. Mills, Todd Tilma +2
It has recently been shown that it is possible to represent the complete quantum state of any system as a phase-space quasi-probability distribution (Wigner function) [Phys Rev Let…
Some implications of superconducting quantum interference to the application of master equations in engineering quantum technologies
S. N. A. Duffus, K. N. Bjergstrøm, V. M. Dwyer +6
In this paper we consider the modelling and simulation of open quantum systems from a device engineering perspective. We derive master equations at different levels of approximatio…
Wigner Functions for Arbitrary Quantum Systems
Todd Tilma, Mark J. Everitt, John H. Samson +2
The possibility of constructing a complete, continuous Wigner function for any quantum system has been a subject of investigation for over 50 years. A key system that has served to…
