Interference of spontaneously emitted photons
Almut Beige, Christian Schoen, Jiannis Pachos
We discuss an experimental setup where two laser-driven atoms spontaneously emit photons and every photon causes a ``click'' at a point on a screen. By deriving the probability den…
Optical Holonomic Quantum Computation
Demosthenes Ellinas, Jiannis Pachos
Holonomic quantum computation (HQC) is materialized here with quantum optics components. Holonomies are the generalization of the Berry phases to unitary matrices with dimensionali…
Quantum computation with trapped ions in an optical cavity
Jiannis Pachos, Herbert Walther
Two-qubit logical gates are proposed on the basis of two atoms trapped in a cavity setup. Losses in the interaction by spontaneous transitions are efficiently suppressed by employi…
Geometric phases of mesoscopic spin in Bose-Einstein condensates
I. Fuentes-Guridi, J. Pachos, S. Bose +2
We propose a possible scheme for generating spin-J geometric phases using a coupled two-mode Bose-Einstein condensate (BEC). First we show how to observe the standard Berry phase u…
