Topological phases and multiqubit entanglement
Markus Johansson, Marie Ericsson, Kuldip Singh +2
Global phase factors of topological origin, resulting from cyclic local evolution, called topological phases, were first described in [Phys. Rev. Lett. {\bf 90}, 230403 (…
Global asymmetry of many-qubit correlations: A lattice gauge theory approach
Mark S. Williamson, Marie Ericsson, Markus Johansson +3
We introduce a novel bridge between the familiar gauge field theory approaches used in many areas of modern physics such as quantum field theory and the SLOCC protocols familiar in…
Geometric local invariants and pure three-qubit states
Mark S. Williamson, Marie Ericsson, Markus Johansson +4
We explore a geometric approach to generating local SU(2) and invariants for a collection of qubits inspired by lattice gauge theory. Each local invariant or 'ga…
Correlation induced non-Abelian quantum holonomies
Markus Johansson, Marie Ericsson, Kuldip Singh +2
In the context of two-particle interferometry, we construct a parallel transport condition that is based on the maximization of coincidence intensity with respect to local unitary…
Quantum Correlations in Mixed-State Metrology
Kavan Modi, Hugo Cable, Mark Williamson +1
We analyze the effects of quantum correlations, such as entanglement and discord, on the efficiency of phase estimation by studying four quantum circuits that can be readily implem…
Violation of multipartite Bell inequalities with classical subsystems via operationally local transformations
Mark S. Williamson, Libby Heaney, Wonmin Son
Recently, it was demonstrated by Son et al., Phys. Rev. Lett. \textbf{102}, 110404 (2009), that a separable bipartite continuous variable quantum system can violate the Clauser-Hor…
