Singularity of type arising from four qubit systems
Frédéric Holweck, Jean-Gabriel Luque, Michel Planat
An intriguing correspondence between four-qubit systems and simple singularity of type is established. We first consider an algebraic variety of separable states within t…

Grassmannian Connection Between Three- and Four-Qubit Observables, Mermin's Contextuality and Black Holes
Peter Levay, Michel Planat, Metod Saniga
We invoke some ideas from finite geometry to map bijectively 135 heptads of mutually commuting three-qubit observables into 135 symmetric four-qubit ones. After labeling the elemen…
