Robust control of quantum systems by quantum systems
Thomas Konrad, Amy Rouillard, Michael Kastner +1
Quantum systems can be controlled by other quantum systems in a reversible way, without any information leaking to the outside of the system-controller compound. Such coherent quan…
Vector mode decay in atmospheric turbulence: a quantum inspired analysis
Isaac Nape, Nikiwe Mashaba, Nokwazi Mphuthi +3
Vector beams are inhomogeneously polarized optical fields with nonseparable, quantum-like correlations between their polarisation and spatial components, and hold tremendous promis…
Solving MKP Applied to IoT in Smart Grid Using Meta-heuristics Algorithms: A Parallel Processing Perspective
Jandre Albertyn, Ling Cheng, Adnan M. Abu-Mahfouz
Increasing electricity prices in South Africa and the imminent threat of load shedding due to the overloaded power grid has led to a need for Demand Side Management (DSM) devices l…
Structured Light in Turbulence
Mitchell A. Cox, Nokwazi Mphuthi, Isaac Nape +3
Optical communication is an integral part of the modern economy, having all but replaced electronic communication systems. Future growth in bandwidth appears to be on the horizon u…
Online Constrained Model-based Reinforcement Learning
Benjamin van Niekerk, Andreas Damianou, Benjamin Rosman
Applying reinforcement learning to robotic systems poses a number of challenging problems. A key requirement is the ability to handle continuous state and action spaces while remai…
A 1000-fold Acceleration of Hidden Markov Model Fitting using Graphical Processing Units, with application to Nonvolcanic Tremor Classification
Marnus Stoltz, Gene Stoltz, Kazushige Obara +2
Hidden Markov models (HMMs) are general purpose models for time-series data widely used across the sciences because of their flexibility and elegance. However fitting HMMs can ofte…
