The field inside a random distribution of parallel dipoles
Janus H. Wesenberg, Klaus Molmer
We determine the probability distribution for the field inside a random uniform distribution of electric or magnetic dipoles. For parallel dipoles, simulations and an analytical de…
Designing robust gate implementations for quantum information processing
Janus H. Wesenberg
Quantum information processing systems are often operated through time dependent controls; choosing these controls in a way that makes the resulting operation insensitive to variat…
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…
