Many thanks for the very helpful comments. In terms of what is entangled, it would be two photons created by spontaneous parametric down-conversion, entangled in polarisation and momentum. I'd like to be able to measure something that would confirm that they are indeed entangled. So as you...

I'm hoping this is a good forum to have dialogue with experts working at the forefront of research. So far, so good!

Many thanks for the good links and works in this area. From looking at these i can now see that what I'm measuring is the Q-function. I can now appreciate both the Q and the Wigner function are both convolutions with the P-function. However, i looking at the texts of the above i didnt see any...

I'm a physicist and engineer from academia and industry, mostly classical physics and engineering, with a growing interest in quantum optics in the microwave and millimetre wave band. I'm interested in novel sensing capabilities and developing technology to exploit this.

Suppose i measure the phase and amplitude of some radiation, this might be a coherent state of an entangled state, how would i construct the Wigner function from these measurements?
