Non-adiabatic holonomic quantum computation
Erik Sjöqvist, D. M. Tong, L. Mauritz Andersson +3
We develop a non-adiabatic generalization of holonomic quantum computation in which high-speed universal quantum gates can be realized by using non-Abelian geometric phases. We sho…
Relative state measures of correlations in bipartite quantum systems
Pierre Rudolfsson, Erik Sjöqvist
Everett's concept of relative state can be viewed as a map that contains information about correlations between measurement outcomes on two quantum systems. We demonstrate how geom…
Non-Abelian quantum holonomy of hydrogen-like atoms
Vahid Azimi Mousolou, Carlo M. Canali, Erik Sjöqvist
We study the Uhlmann holonomy [Rep. Math. Phys. 24, 229 (1986)] of quantum states for hydrogen-like atoms where the intrinsic spin and orbital angular momentum are coupled by the s…
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…
