Geometric quantum gate for trapped ions based on optical dipole forces induced by Gaussian laser beams
Peter Staanum, Michael Drewsen, Klaus Moelmer
We present an implementation of quantum logic gates via internal state dependent displacements of ions in a linear Paul trap caused by optical dipole forces. Based on a general qua…
Robust quantum gates and a bus architecture for quantum computing with rare-earth-ion doped crystals
Janus Wesenberg, Klaus Moelmer
We present a composite pulse controlled phase gate which together with a bus architecture improves the feasibility of a recent quantum computing proposal based on rare-earth-ion do…
Mixed collective states of many spins
Janus Wesenberg, Klaus Moelmer
Mixed states of samples of spin s particles which are symmetric under permutations of the particles are described in terms of their total collective spin quantum numbers. We use th…
Spin squeezing of atoms by Rydberg blockade
Isabelle Bouchoule, Klaus Moelmer
We show that the interaction between Rydberg atomic states can provide continuous spin squeezing of atoms with two ground states. The interaction prevents the simultaneous excitati…
