Sorensen bound for the maximum transfer efficiency between two states under arbitrary control operators. Equation 186 from https://doi.org/10.1016/0079-6565(89)80006-8.

Syntax

    b=sorensen(rho_init,rho_targ)

Arguments

   rho_init  - initia ldensity matrix, Hilbert space

   rho_targ  - target density matrix, Hilbert space

Outputs

   b         - Sorensen bound

Notes

This is an exact unitary bound; the amount reachable with realistically available instrumental controls may be smaller, see the detailed analysis here: https://doi.org/10.1080/00268979909483117
