Open Systems & Information Dynamics, 2007
Fundamental studies of quantum measurements and their capacity to acquire information are typically based on scenarios in which the full Hilbert space of the measured quantum system is open to measurement interactions. In this work, we consider a class of incomplete quantum measurements — quantum subspace measurements (QSM's) — for which all ...

Physical Review Letters, 1986
Our formalism for describing quantum measurements is generalized to the multitime case and used to derive rigorous time-energy uncertainty relations. For a free particle, we find that $T\ensuremath{\delta}H\ensuremath{\ge}\frac{1}{2}$, where $\ensuremath{\delta}H$ is the dispersion in energy and $T$ is the measurement duration as given by an external ...

Foundations of Quantum Mechanics, 1991
Abstract The “quantum measurement problem” deals with the reconciliation of the microscopic with the macroscopic . In this article (which has a review component) we describe a theory that effects that reconciliation through a radical revision of (experimentally unverified aspects of) the fundamental hypotheses of statistical mechanics, the latter ...

The Quantum Measurement Problem
Science, 2005Despite the spectacular success of quantum mechanics (QM) over the last 80 years in explaining phenomena observed at the atomic and subatomic level, the conceptual status of the theory is still a topic of lively controversy. Most of the discussion centers around two famous paradoxes (or, as some would have it, pseudoparadoxes) associated, respectively,

Information and quantum measurement
IEEE Transactions on Information Theory, 1978Given a finite number of quantum states with {\em a priori} probabilities, the positive operator-valued measure that maximizes the Shannon mutual information is investigated. The group covariant case is examined in detail.
