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…
Efficient verification and fidelity estimation of discrete bipartite squeezed states
Russell P Rundle
To gain an advantage, quantum technologies utilize phenomena particular to quantum mechanics. Two such phenomena are squeezing and entanglement. Having generated states that exhibi…
Overview of the phase space formulation of quantum mechanics with application to quantum technologies
Russell P Rundle, Mark J Everitt
The phase-space formulation of quantum mechanics has recently seen increased use in testing quantum technologies, including metho ds of tomography for state verification and device…
Visualization of correlations in hybrid quantum systems
R. P. Rundle, B. I. Davies, V. M. Dwyer +2
In this work we construct Wigner functions for hybrid continuous and discrete variable quantum systems. We demonstrate new capabilities in the visualization of the interactions and…
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…
