POVM generated quantum trajectories without stochastic differential equations

Rutvij Bhavsar, N. D. Hari Dass

In this paper we examine the issue of quantum trajectories generated by QND-POVM's on {\it single} copies of unknown states. After an introduction to various aspects of quantum mea…

Dirac and the Path Integral

N. D. Hari Dass

Through a very careful analysis of Dirac's 1932 paper on the Lagrangian in Quantum Mechanics as well as the second and third editions of his classic book {\it The Principles of Qua…

Optimal weak measurements: Mixed States

N. D. Hari Dass, R. Rajath Krishna

In an earlier publication we had given an exhaustive analysis of the criteria for weak value measurements of pure states to be optimal in the sense considered by Wootters and Field…

Optimal weak value measurements: Pure states

N. D. Hari Dass, R. Rajath Krishna, Sai Smruti Samantaray

We apply the notion of \emph{optimality} of measurements for state determination(tomography) as originally given by Wootters and Fields to \emph{weak value tomography} of \emph{pur…

Bell-like examples for spin-1 hidden variable theories

Kaushik Borah, N. D. Hari Dass

Though John Bell had claimed that his spin-1/2 example of a hidden-variable theory(HV) is an \emph{explicit} counterexample to von Neumann's proof of the non-existence of hidden va…

Three results on weak measurements

N. D. Hari Dass

Three recent results on weak measurements are presented. They are: i) repeated measurements on a single copy can not provide any information on it and further, that in the limit of…
