Estimation of quantum states and operations

I have studied the application of Bayesian methods to estimate single-qubit logic gates in the presence of phase noise. The protocol has been also experimentally verified (Phys. Rev. A in 2010) and successfully extended to the continuous-variable regime in the case of homodyne interferometry (Phys. Rev. Lett. in 2011 and Phys. Rev. A in 2012). In the field of estimation of quantum states, I have also collaborated on the development of protocols based on maximum likelihood methods (MaxLik) for the reconstruction of quantum states.

I also investigate new approaches to improve estimation strategies (Entropy in 2021, Quantum Sci. Technol. 2022).
