Quantum metrology paper in PRA

Christos, Dominic and Animesh's paper on quantum-enhanced estimation of multiple phase parameters has been published in Physical Review A. It looks at fundamental bounds on the performance of Gaussian states for estimation of multiple phase parameters and the advantage gained over multiple individual estimation strategies. The results also suggest that the optimal states for single phase estimation do not necessarily have the same performance when generalised to the estimation of multiple similar parameters.
