We present a self-consistent theoretical framework for finite-dimensional discrete phase spaces that leads us to establish a well-grounded mapping scheme between Schwinger unitary operators and generators of the special unitary group . This general mathematical construction provides a sound pathway to the formulation of a genuinely discrete Wigner function for arbitrary quantum systems described by finite-dimensional state vector spaces. To illustrate our results, we obtain a general discrete…

Representations of two-qubit and ququart states via discrete Wigner functions
By means of a well-grounded mapping scheme linking Schwinger unitary operators and generators of the special unitary group $\mathrm{SU(N)}$, it is possible to establish a self-consistent theoretical
Generalized spin mapping for quantum-classical dynamics.
TLDR
A spin-mapping approach based on the well-known quantum equivalence between a two-level system and a spin-1/2 particle is generalized to describe the dynamics of N-level systems and derives a simple way to approximate correlation functions in complex nonadiabatic molecular systems via classical trajectories.
Overview of the Phase Space Formulation of Quantum Mechanics with Application to Quantum Technologies
TLDR
An overview of quantum mechanics in phase space is presented, and the formulation to generate a generalized phase-space function for any arbitrary quantum system is shown, such as the Wigner and Weyl functions along with the Q and P functions.
New phase space formulations and quantum dynamics approaches
We report recent progress on the phase space formulation of quantum mechanics with coordinate-momentum variables, focusing more on new theory of (weighted) constraint coordinate-momentum phase space
