Quantum bayes rule

R Schack, TA Brun, CM Caves - Physical Review A, 2001 - APS
We state a quantum version of the Bayes rule for statistical inference and give a simple
general derivation within the framework of generalized measurements. The rule can be …

Fundamental limits upon the measurement of state vectors

KRW Jones - Physical Review A, 1994 - APS
Using the Shannon information theory and the Bayesian methodology for inverting quantum
data [KRW Jones, Ann. Phys.(NY) 207, 140 (1991)] we prove a fundamental bound upon the …

Amount of information obtained by a quantum measurement

S Massar, S Popescu - Physical Review A, 2000 - APS
In this paper we address the problem of how much can be learned about an unknown
quantum state by a measurement. To this end we consider optimal measurements for the …

Quantum state reconstruction from incomplete data

V Buzek, G Drobny, R Derka, G Adam… - arXiv preprint quant-ph …, 1998 - arxiv.org
Knowing and guessing, these are two essential epistemological pillars in the theory of
quantum-mechanical measurement. As formulated quantum mechanics is a statistical …

Discriminating states: The quantum Chernoff bound

KMR Audenaert, J Calsamiglia, R Munoz-Tapia… - Physical review …, 2007 - APS
We consider the problem of discriminating two different quantum states in the setting of
asymptotically many copies, and determine the minimal probability of error. This leads to the …

Quantum state discrimination bounds for finite sample size

KMR Audenaert, M Mosonyi… - Journal of Mathematical …, 2012 - pubs.aip.org
In the problem of quantum state discrimination, one has to determine by measurements the
state of a quantum system, based on the a priori side information that the true state is one of …

Fisher information in quantum statistics

OE Barndorff-Nielsen, RD Gill - Journal of Physics A …, 2000 - iopscience.iop.org
Abstract Braunstein and Caves (Braunstein SL and Caves CM 1994 Phys. Rev. Lett. 72
3439-43) proposed to use Helstrom's quantum information number to define, meaningfully, a …

Quantum probabilities as Bayesian probabilities

CM Caves, CA Fuchs, R Schack - Physical review A, 2002 - APS
In the Bayesian approach to probability theory, probability quantifies a degree of belief for a
single trial, without any a priori connection to limiting frequencies. In this paper, we show …

Quantum-state reconstruction by maximizing likelihood and entropy

YS Teo, H Zhu, BG Englert, J Řeháček, Z Hradil - Physical review letters, 2011 - APS
Quantum-state reconstruction on a finite number of copies of a quantum system with
informationally incomplete measurements, as a rule, does not yield a unique result. We …

Quantum Chernoff bound as a measure of distinguishability between density matrices: Application to qubit and Gaussian states

J Calsamiglia, R Munoz-Tapia, L Masanes, A Acin… - Physical Review A …, 2008 - APS
Hypothesis testing is a fundamental issue in statistical inference and has been a crucial
element in the development of information sciences. The Chernoff bound gives the minimal …
