In situ characterization of a photon-subtraction device via heralding counts and homodyne detection
Priyanka Sharma, Matteo G. A. Paris, Stefano Olivares
Photon subtraction is one of the most important techniques for generating non-Gaussian optical states and constitutes a key resource for quantum information processing and quantum…
Quadratic and cubic scrambling in the estimation of two successive phase-shifts
Manju, Stefano Olivares, Matteo G. A. Paris
Multiparameter quantum estimation becomes challenging when the parameters are incompatible, i.e., when their respective symmetric logarithmic derivatives do not commute, or when th…
Measuring spatial coherence of quantum and classical light with an ultrastable monolithic interferometer
Edoardo Suerra, Mirko Siano, Bruno Paroli +4
We describe a monolithic interferometer for spatial coherence measurements of both classical and quantum light sources. The design combines parametric down-conversion with a therma…
Mitigating sloppiness in joint estimation of successive squeezing parameters
Priyanka Sharma, Stefano Olivares, Devendra Kumar Mishra +1
When two successive squeezing operations with the same phase are applied to a field mode, reliably estimating the amplitude of each is impossible because the output state depends s…
The ultimate bounds to precision of atomic clock frequency measurement techniques
Stefano Olivares, Salvatore Micalizio, Matteo G. A. Paris
We investigate the ultimate quantum limits to the achievable uncertainty in the estimation of the transition frequency between two atomic levels. We focus on Rabi, Ramsey, and cohe…
Joint estimation of noise and nonlinearity in Kerr systems
Michele N. Notarnicola, Stefano Olivares, Matteo G. A. Paris
We address characterization of lossy and dephasing channels in the presence of self-Kerr interaction using coherent probes. In particular, we investigate the ultimate bounds to pre…
