Highly robust logical qubit encoding in an ensemble of V-symmetrical qutrits
Luis Octavio Castaños-Cervantes, Manuel Calixto, Julio Guerrero
We propose using even and odd Schödinger cat states formed from coherent states of U(3) of an ensemble of qutrits with a symmetrical V-configuration (a qubit-disguised qutrit) to…

Wigner quasi-probability distribution for symmetric multi-quDit systems and their generalized heat kernel
Manuel Calixto, Julio Guerrero
For a symmetric -quDit system described by a density matrix , we construct a one-parameter family of quasi-probability distributions through gener…

Lieb-Mattis ordering theorem of electronic energy levels in the thermodynamic limit
Manuel Calixto, Alberto Mayorgas, Julio Guerrero
Lieb-Mattis theorem orders the lowest-energy states of total spin of a system of interacting fermions. We generalize these predictions to fermionic mixtures of particle…
