Optimal jump operators for monitoring entanglement — •Olivier Brodier, M. Busse, C. Viviescas, A. R. R. de Carvalho, and A. Buchleitner — M.P.I.P.K.S. Nothnitzer Str. 38 D-01187 DRESDEN GERMANY

We present a simple procedure which gives analytically the short time behaviour of entanglement of an initially pure state coupled to a Markovian bath.

The derivation exhibits an optimal choice of jump operators which unravel the evolution of the reduced density operator.

The method is straightforward for a bipartite 2 levels system, and can be extended approximately to multipartite cases.
