- Abstract: The Witting configuration with 40 complex rays was suggested as a possible
reformulation of Penrose model with two spin-3/2 systems based on geometry of
dodecahedron and used for analysis of nonlocality and contextuality in quantum
mechanics. Yet another configuration with 120 quantum states is considered in
presented work. Despite of different number of states both configurations can
be derived from complexification of 240 minimal vectors of 8D real lattice
corresponding to root system of Lie algebra $E_8$. An analysis of properties of
suggested configuration of quantum states is provided using many analogies with
properties of Witting configuration.

We show that one can recover a QSP-type ansatz, and show its ability to approximate near arbitrary transformations.
We discuss various experimental uses of this construction, as well as prospects for expanded relevance of QSP-like ans"atze to other Lie groups.

A model with two entangled spin-3/2 particles based on geometry of dodecahedron was suggested by Roger Penrose.
The model was later reformulated using so-called Witting configuration with 40 rays in 4D Hilbert space.
Two entangled systems with quantum states described by Witting configurations are discussed in presented work.

We characterize entanglement subject to its definition over real and complex, composite quantum systems.
