Magnon-magnon entanglement and its detection in a microwave cavity
Vahid Azimi Mousolou, Yuefei Liu, Anders Bergman +5
Quantum magnonics is an emerging research field, with great potential for applications in magnon based hybrid systems and quantum information processing. Quantum correlation, such…
Geometric phase of very slow neutrons
Erik Sjöqvist
The geometric phase (GP) acquired by a neutron passing through a uniform magnetic field elucidates a subtle interplay between its spatial and spin degrees of freedom. In the standa…
Parallelity of mixed quantum ensembles
Erik Sjöqvist
A unifying framework for identifying distance and holonomy for decompositions of density operators is introduced. Parallelity between quantum ensembles is defined by minimizing thi…
Geometry along Evolution of Mixed Quantum States
Erik Sjöqvist
The metric underlying the mixed state geometric phase in unitary and nonunitary evolution [Phys. Rev. Lett. {\bf 85}, 2845 (2000); Phys. Rev. Lett. {\bf 93}, 080405 (2004)] is deli…
Proposed neutron interferometry test of Berry's phase for a circulating planar spin
Erik Sjöqvist
The energy eigenstates of a spin particle in a magnetic field confined to a plane, define a planar spin. If the particle moves adiabatically around a loop in this pla…
Bifurcation in Quantum Measurement
Karl-Erik Eriksson, Martin Cederwall, Kristian Lindgren +1
We present a generic model of (non-destructive) quantum measurement. Being formulated within reversible quantum mechanics, the model illustrates a mechanism of a measurement proces…
