Maximum likelihood state between measurements

Alfredo Luis

Abstract

We estimate the quantum state of a system between two measurements via a maximum likelihood strategy. This incorporates all the information provided by preselection and postselection in a legitimate quantum state. Moreover, it allows to include any other constraint derived from practical considerations.

Quantum measurement and estimation

Z. Hradil, Jaroslav Řeháček

Information about quantum systems is inferred from a sequence of measurements made on it. The maximum likelihood (ML) estimation gives an arguably natural optimum approach in quantum theory. The feasibility is shown on valuable examples including quantum phase or entangled spin states.

MAXIMUM LIKELIHOOD ESTIMATION FOR A GROUP OF PHYSICAL TRANSFORMATIONS

Giulio Chiribella, Giacomo Mauro D’Ariano, Paolo Perinotti +1 more

The maximum likelihood strategy for the estimation of group parameters allows one to derive in a general fashion optimal measurements, optimal signal states, and their relations with other information theoretical quantities. These results provide deep insight into the general structure underlying optimal quantum estimation strategies. The entanglement between representation spaces and multiplicity spaces of the group action appears to be the unique kind of entanglement which is really useful for the optimal estimation of group parameters.

Knowledge and ignorance in quantum state estimation

Z. Hradil, Jaroslav Řeháček

An overview of quantum reconstruction methods based on statistical interpretation is presented. In realistic experiments there is always a part of missing information yielding additional ambiguities. Robust estimation strategy based on maximum entropy and maximum likelihood estimation gives the optimal trade-off between ignorance and knowledge.

Maximum-likelihood estimation of the density matrix

Konrad Banaszek, Giacomo Mauro D’Ariano, Matteo G. A. Paris +1 more

We present a universal technique for quantum-state estimation based on the maximum-likelihood method. This approach provides a positive-definite estimate for the density matrix from a sequence of measurements performed on identically prepared copies of the system. The method is versatile and can be applied to multimode radiation fields as well as to spin systems. The incorporation of physical constraints, which is natural in the maximum-likelihood strategy, leads to a substantial reduction of statistical errors. Numerical implementation of the method is based on a particular form of the Gauss decomposition for positive-definite Hermitian matrices.

Quantum theory of incompatible observations

Z. Hradil, J Summhammer

The question of what information about a quantum state may be inferred from a sequence of measurements made on it, is addressed. The main result is that maximum-likelihood estimation gives an arguably natural optimum approach in quantum theory. It singles out a particular choice of basis, in which the state is expressed. Various incompatible and incomplete observations made on the ensemble are treated as a complete generalized measurement. Consequently, the maximum likelihood (relative entropy) is the best measure for relating experimental data with theoretical predictions of quantum theory.

Maximum-likelihood estimation of quantum measurement

Jaromı́r Fiurášek

Maximum-likelihood estimation is applied to the determination of an unknown quantum measurement. The calibrated measuring apparatus carries out measurements on many different quantum states and the positive operator-valued measure governing the measurement statistics is then inferred from the collected data via the maximum-likelihood principle. In contrast to the procedures based on linear inversion, our approach always provides a physically sensible result. We illustrate the method on the case of the Stern-Gerlach apparatus.
