The goal of this article is to provide a largely self-contained introduction to the modelling of
controlled quantum systems under continuous observation, and to the design of feedback …

Feedback control of quantum mechanical systems must take into account the probabilistic
nature of quantum measurement. We formulate quantum feedback control as a problem of …

We characterize the long-time projective behavior of the stochastic master equation
describing a continuous, collective spin measurement of an atomic ensemble both …

We introduce a fast and accurate heuristic for adaptive tomography that addresses many of
the limitations of prior methods. Previous approaches were either too computationally …

We demonstrate a fast, robust, and nondestructive protocol for quantum-state estimation
based on continuous weak measurement in the presence of a controlled dynamical …

We evaluate the performance of quantum arithmetic algorithms run on a distributed quantum
computer (a quantum multicomputer). We vary the node capacity and I/O capabilities, and …

Trapping of 10-nm-sized single fluorescent bio-molecules in solution has been achieved
using high-speed position sensing and electrokinetic feedback forces in the Anti-Brownian …

Quantum computing (QC) offers the ability to efficiently solve certain computational problems
which are intractable classically. Recently, most of the requirements for QC have been …

We describe a general purpose digital servo optimized for feedback control of lasers in
atomic, molecular, and optical physics experiments. The servo is capable of feedback …

The quantum multicomputer consists of a large number of small nodes and a qubus
interconnect for creating entangled state between the nodes. The primary metric chosen is …
