Group theoretic formulation of complementarity
J. A. Vaccaro
We generalize Bohr's complementarity principle for wave and particle properties to arbitrary quantum systems. We begin by noting that a particle-like state is represented by a spat…
A Very Fast Algorithm for Matrix Factorization
Vladimir Nikulin, Tian-Hsiang Huang, Shu-Kay Ng +2
We present a very fast algorithm for general matrix factorization of a data matrix for use in the statistical analysis of high-dimensional data via latent factors. Such data are pr…
How many bits does it take to track an open quantum system?
R. I. Karasik, H. M. Wiseman
A -dimensional Markovian open quantum system will undergo quantum jumps between pure states, if we can monitor the bath to which it is coupled with sufficient precision. In gene…
Measuring measurement--disturbance relationships with weak values
A. P. Lund, H. M. Wiseman
Using formal definitions for measurement precision ε and disturbance (measurement backaction) η, Ozawa [Phys. Rev. A 67, 042105 (2003)] has shown that Heisenberg's claimed relation…
Imaging trapped ions with a microfabricated lens for quantum information processing
Erik W. Streed, Benjamin G. Norton, Andreas Jechow +2
Trapped ions are a leading system for realizing quantum information processing (QIP). Most of the technologies required for implementing large-scale trapped-ion QIP have been demon…
Rapid purification of quantum systems by measuring in a feedback-controlled unbiased basis
Joshua Combes, Howard M. Wiseman, Kurt Jacobs +1
Rapid-purification by feedback --- specifically, reducing the mean impurity faster than by measurement alone --- can be achieved by making the eigenbasis of the density matrix to b…
