Discrete wigner functions and the phase-space representation of quantum teleportation
A phase-space description of the process of quantum teleportation for a system with an N-dimensional space of states was discussed. A discrete Wigner function was used to represent a composite quantum system in phase space and to analyse entanglement between subsystems. The process to use Wigner fun...

| Sumario: | A phase-space description of the process of quantum teleportation for a system with an N-dimensional space of states was discussed. A discrete Wigner function was used to represent a composite quantum system in phase space and to analyse entanglement between subsystems. The process to use Wigner function for tomographic measurement was also discussed. |
