694. Quantum Squeezing using Self-Induced Transparency

Joel Corney (The University of Queensland)

ANZOS | Quantum and Atom Optics (ANZCOP QAO)

Invited talk

Self-induced transparency (SIT) is a highly nonlinear effect in which a resonant (or near resonant) pulse of light propagates losslessly in a medium via a coherent cycle of absorption and stimulated emission. Here we study the use of SIT for creating squeezed states of light through both nonlinear phase-shifts (quadrature squeezing) and nonlinear absorption (amplitude squeezing). In...

700. Quantum Circuit Fragments and Link Products in Continuous Variables

Contributed Oral

Many quantum-information tasks do not neatly fit the picture of a single quantum process acting on an input state to produce an output to be measured. For example, a probe of a system need not be a one-shot measurement, but a series of interventions adapted based on a previous time-step. The dynamics being probed may also be non-Markovian, where the presence of memory may imply that the...

725. Demonstrating a spin dependent force to push a 128mg levitated diamond towards quantum sensing and generating macroscopic quantum superpositions

The force experienced by a spin in a magnetic field gradient underlies many proposals for hybrid quantum systems. These include schemes for mechanically mediated quantum gates, spin squeezing, searches for exotic forces, and motional superpositions for probing the interface between quantum and gravity. Yet, experimentally observing this spin-force for anything larger than atomic scales has...

453. Ultimate sensitivity of multiparameter estimation in quantum sensing with undetected photons

Sanjeet Swaroop Panda (Australian National University and Q Inc Astar)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Quantum sensing with undetected photons is a technique in which a sample is probed by photons of one wavelength, while information about the sample is extracted by measuring photons of a different wavelength that never interacts with it. This approach has enabled significant experimental advances in spectroscopy, microscopy, and bio-sensing. Despite this progress, a detailed theoretical...

368. Non-Gaussian Photon Correlations in Weakly Coupled Atomic Ensembles

Yangming Wang (the University of Sydney)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

We develop a scattering theory formalism and use it to predict that a resonantly driven atomic ensemble weakly coupled to an optical mode can generate light with non-Gaussian correlations. Our approach -- based on a perturbative diagrammatic expansion of multi-photon interactions -- shows that photon-photon interaction mediated by the emitters causes the transmitted light to have a...
