Single-photon orbital angular momentum qudit states in fiber - Limits to Dephasing correction via dynamical decoupling
Manish K. Gupta, Jonathan P. Dowling
We analytically derive a decoherence model for orbital angular momentum states of a photon in a multimode optical fiber and show that rate of decoherence scales exponentially with…
A Method for Generating All Uniform -Pulse Sequences Used in Deterministic Dynamical Decoupling
Haoyu Qi, Jonathan P. Dowling
Dynamical decoupling has been actively investigated since Viola first suggested using a pulse sequence to protect a qubit from decoherence. Since then, many schemes of dynamical de…
Implementing Scalable Boson Sampling with Time-Bin Encoding: Analysis of Loss, Mode Mismatch, and Time Jitter
Keith R. Motes, Jonathan P. Dowling, Alexei Gilchrist +1
It was recently shown by Motes, Gilchrist, Dowling & Rohde [PRL 113, 120501 (2014)] that a time-bin encoded fiber-loop architecture can implement an arbitrary passive linear optics…
Quantum Hall effect with small numbers of vortices in Bose-Einstein condensates
Tim Byrnes, Jonathan P. Dowling
When vortices are displaced in Bose-Einstein condensates (BEC), the Magnus force gives the system a momentum transverse in the direction to the displacement. We show that Bose-Eins…
Spatial Multi-Mode Structure of Atom-Generated Squeezed Light
Mi Zhang, R. Nicholas Lanning, Zhihao Xiao +3
We investigated the spatial distribution of quantum fluctuations in a squeezed vacuum field, generated via polarization self-rotation (PSR) interaction of an ensemble of Rb atoms a…
Sagnac interferometry with coherent vortex superposition states in exciton-polariton condensates
Frederick Ira Moxley, Jonathan P. Dowling, Weizhong Dai +1
We investigate prospects of using counter-rotating vortex superposition states in non-equilibrium exciton-polariton Bose-Einstein condensates for the purposes of Sagnac interferome…
