Information geometry and local asymptotic normality for multi-parameter estimation of quantum Markov dynamics (2017)
Journal Article
Guţă, M., & Kiukas, J. (in press). Information geometry and local asymptotic normality for multi-parameter estimation of quantum Markov dynamics. Journal of Mathematical Physics, 58, https://doi.org/10.1063/1.4982958

This paper deals with the problem of identifying and estimating dynamical parameters of continuous-time Markovian quantum open systems, in the input-output formalism. First, we characterise the space of identifiable parameters for ergodic dynamics, a...

Statistical analysis of compressive low rank tomography with random measurements (2017)
Journal Article
Acharya, A., & Guţă, M. (in press). Statistical analysis of compressive low rank tomography with random measurements. Journal of Physics A: Mathematical and Theoretical, 50(19), https://doi.org/10.1088/1751-8121/aa682e

We consider the statistical problem of 'compressive' estimation of low rank states (r«d ) with random basis measurements, where r, d are the rank and dimension of the state respectively. We investigate whether for a fixed sample size N, the estimatio... Read More about Statistical analysis of compressive low rank tomography with random measurements.

Identification of single-input–single-output quantum linear systems (2017)
Journal Article
Levitt, M., & Guţă, M. (in press). Identification of single-input–single-output quantum linear systems. Physical Review A, 95(3), Article 033825. https://doi.org/10.1103/PhysRevA.95.033825

The purpose of this paper is to investigate system identification for single-input–single-output general (active or passive) quantum linear systems. For a given input we address the following questions: (1) Which parameters can be identified by measu... Read More about Identification of single-input–single-output quantum linear systems.
