Dynamics and manipulation of entanglement in coupled harmonic systems with many degrees of freedom
M. B. Plenio, J. Hartley, J. Eisert
We study the entanglement dynamics of a system consisting of a large number of coupled harmonic oscillators in various configurations and for different types of nearest neighbour i…

Towards mechanical entanglement in nano-electromechanical devices
J. Eisert, M. B. Plenio, S. Bose +1
We study arrays of mechanical oscillators in the quantum domain and demonstrate how the motions of distant oscillators can be entangled without the need for control of individual o…

Entropy as a function of Geometric Phase
Julian Hartley, Vlatko Vedral
We give a closed-form solution of von Neumann entropy as a function of geometric phase modulated by visibility and average distinguishability in Hilbert spaces of two and three dim…
