Cavity enhanced Raman heterodyne spectroscopy in Er:YSO for microwave to optical signal conversion
Xavier Fernandez-Gonzalvo, Sebastian P. Horvath, Yu-Hui Chen +1
The efficiency of the frequency conversion process at the heart of Raman heterodyne spectroscopy was improved by nearly four orders of magnitude by resonant enhancement of both the…
Mesoscopic dynamical differences from quantum state preparation in a Bose-Hubbard trimer
M. K. Olsen, T. W. Neely, A. S. Bradley
Conventional wisdom is that quantum effects will tend to disappear as the number of quanta in a system increases, and the evolution of a system will become closer to that described…
Quantum correlations across two octaves from combined up and down conversion
Jingyan Li, M. K. Olsen
We propose and analyse a cascaded optical parametric system which involves three interacting modes across two octaves of frequency difference. Our system, combining degenerate opti…
Spin effects on the semiclassical trajectories of Dirac electrons
R. Gutierrez-Jauregui, R. Perez-Pascual, R. Jauregui
The relativistic semiclassical evolution of the position of an electron in the presence of an external electromagnetic field is studied in terms of a Newton equation that incorpora…
Optimal Matterwave Gravimetry
Michail Kritsotakis, Stuart S. Szigeti, Jacob A. Dunningham +1
We calculate quantum and classical Fisher informations for gravity sensors based on matterwave interference, and find that current Mach-Zehnder interferometry is not optimally extr…
Entanglement and asymmetric steering over two octaves of frequency difference with cascaded harmonic generation
M. K Olsen
We analyse a nonlinear optical system which uses cascaded nonlinearities to produce both second and fourth harmonic outputs from an input field at the fundamental frequency. Using…
Cavity QED engineering of spin dynamics and squeezing in a spinor gas
Stuart J. Masson, M. D. Barrett, Scott Parkins
We propose a method for engineering spin dynamics in ensembles of integer-spin atoms confined within a high-finesse optical cavity. Our proposal uses cavity-assisted Raman transiti…
Controlled asymmetry of EPR steering with an injected non-degenerate optical parametric oscillator
M. K. Olsen
We propose and analyse a nonlinear optical apparatus in which the direction of asymmetric steering is controllable within the apparatus, rather than by adding noise to measurements…
Entanglement properties of third harmonic generation via direct and cascaded parametric processes
M. K. Olsen
We compare the bipartite entanglement and EPR-steering properties of the two different schemes which produce third harmonic optical fields from an input field at the fundamental fr…
Rydberg excitation of cold atoms inside a hollow core fiber
Maria Langbecker, Mohammad Noaman, Niels Kjærgaard +2
We report on a versatile, highly controllable hybrid cold Rydberg atom fiber interface, based on laser cooled atoms transported into a hollow core Kagomé crystal fiber. Our experim…
Optimal and Robust Quantum Metrology Using Interaction-Based Readouts
Samuel P. Nolan, Stuart S. Szigeti, Simon A. Haine
Useful quantum metrology requires nonclassical states with a high particle number and (close to) the optimal exploitation of the state's quantum correlations. Unfortunately, the si…
Open quantum systems with delayed coherent feedback
S. J. Whalen, A. L. Grimsmo, H. J. Carmichael
We present an elementary derivation and generalisation of a recently reported method of simulating feedback in open quantum systems. We use our generalised method to simulate syste…
A versatile apparatus for two-dimensional atomtronic quantum simulation
T. A. Haase, D. H. White, D. J. Brown +2
We report on the implementation of a novel optical setup for generating high-resolution customizable potentials to address ultracold bosonic atoms in two dimensions. Two key featur…
