  The dynamics of any quantum system is unavoidably influenced by the external
environment. Thus, the observation of a quantum system (probe) can allow the
measure of the environmental features. Here, to spectrally resolve a noise
field coupled to the quantum probe, we employ dissipative manipulations of the
probe, leading to so-called Stochastic Quantum Zeno (SQZ) phenomena. A quantum
system coupled to a stochastic noise field and subject to a sequence of
protective Zeno measurements slowly decays from its initial state with a
survival probability that depends both on the measurement frequency and the
noise. We present a robust sensing method to reconstruct the unkonwn noise
power spectral density by evaluating the survival probability that we obtain
when we additionally apply a set of coherent control pulses to the probe. The
joint effect of coherent control, protective measurements and noise field on
the decay provides us the desired information on the noise field.
