Optimal Discrimination of Mixed Symmetric Multi-mode Coherent States
Ioannis Petrongonas, Erika Andersson
We find the optimal measurement for distinguishing between symmetric multi-mode phase-randomized coherent states. A motivation for this is that phase-randomized coherent states can…

Experimental observation of anomalous topological edge modes in a slowly-driven photonic lattice
Sebabrata Mukherjee, Alexander Spracklen, Manuel Valiente +4
The discovery of the quantised Hall effect, and its subsequent topological explanation, demonstrated the important role topology can play in determining the properties of quantum s…
