The control of individual quantum systems is now a reality in a variety of physical settings.
Feedback control is an important class of control methods because of its ability to reduce the …

We review experimental progress on atom lasers out-coupled from Bose–Einstein
condensates, and consider the properties of such beams in the context of precision inertial …

The purpose of this paper is to study and design direct and indirect couplings for use in
coherent feedback control of a class of linear quantum stochastic systems. A general …

All light has structure, but only recently it has become possible to construct highly
controllable and precise potentials so that most laboratories can harness light for their …

We introduce a theoretical framework for single-shot phase contrast imaging (PCI)
measurements of spinor Bose-Einstein condensates (BECs). Our model allows for the …

The dispersive interaction of atoms and a far-detuned light field allows nondestructive
imaging of the density oscillations in Bose-Einstein condensates. Starting from a ground …

We shift the paradigm of feedback control from the control of quantum states to the control of
phase transitions in quantum systems. We show that feedback allows tuning the universality …

We investigate the prospect of enhancing the phase sensitivity of atom interferometers in the
Mach-Zehnder configuration with squeezed light. Ultimately, this enhancement is achieved …

Off-resonant optical imaging is a popular method for continuous monitoring of a Bose–
Einstein condensate. However, the disturbance caused by scattered photons places a …

We calculate quantum and classical Fisher information for gravity sensors based on matter-
wave interference, and find that current Mach-Zehnder interferometry is not optimally …
