Continuous quantum nondemolition feedback and unconditional atomic spin squeezing
L. K. Thomsen, S. Mancini, H. M. Wiseman
We discuss the theory and experimental considerations of a quantum feedback scheme for producing deterministically reproducible spin squeezing. Continuous nondemolition atom number…
Spin squeezing via quantum feedback
L. K. Thomsen, S. Mancini, H. M. Wiseman
We propose a quantum feedback scheme for producing deterministically reproducible spin squeezing. The results of a continuous nondemolition atom number measurement are fed back to…
Atom laser coherence and its control via feedback
L. K. Thomsen, H. M. Wiseman
We present a quantum-mechanical treatment of the coherence properties of a single-mode atom laser. Specifically, we focus on the quantum phase noise of the atomic field as expresse…
Effects of twin-beam squashed light on a three-level atom
L. K. Thomsen, H. M. Wiseman
An electro-optical feedback loop can make in-loop light (squashed light) which produces a photocurrent with noise below the standard quantum limit (such as squeezed light). We inve…
Reducing the linewidth of an atom laser by feedback
H. M. Wiseman, L. K. Thomsen
A continuous atom laser will almost certainly have a linewidth dominated by the effect of the atomic interaction energy, which turns fluctuations in the condensate atom number into…
