The topological spectrum of high dimensional quantum states
Robert de Mello Koch, Pedro Ornelas, Neelan Gounden +3
Topology has emerged as a fundamental property of many systems, manifesting in cosmology, condensed matter, high-energy physics and waves. Despite the rich textures, the topology h…

Quantum Skyrmions in general quantum channels: topological noise rejection and the discretization of quantum information
Robert de Mello Koch, Bo-Qiang Lu, Pedro Ornelas +2
The topology of a pure state of two entangled photons is leveraged to provide a discretization of quantum information. Since discrete signals are inherently more resilient to the e…
