How to measure the photon number parity of cavity?

Let's say system A is your "memory", i.e. it encodes the quantum information and you want it to be isolated from the environment. Imagine you have another system B in the circuit, with which you can interact, and which you can measure.

If system B is coupled to A in a certain way, its resonance frequency $f_B$ will change depending on the number of photons in system A:

$$ f_B = f_0 + n \chi $$
