NAZOV / TITLE :

Some Geometrical Aspects of Quantum Contextuality

ABSTRAKT / ABSTRACT :

We shall introduce an intriguing geometric representation
of a three-qubit quantum contextual configuration known as Mermin
pentagram. By replacing its observables by doilies it will be shown
what commuting/anticommuting means geometrically. Extending this
process to doilies will enable us to unveil two different kinds of
contexts that would otherwise go unnoticed.
