|We show that finding the optimal measurement on the environment
for stationary Linear Quadratic Gaussian control problems is a semi-definite
program. We apply this technique to the control of the entanglement between
two bosonic modes interacting via a parametric Hamiltonian at steady state.
The optimal measurement turns out to be nonlocal.
We also find the optimal local measurement and control technique.
