Con el fin de codificar  más información,  las aplicaciones cuánticas buscan aumentar la dimensionalidad  del espacio de Hilbert. En este artículo, reportamos nuestros esfuerzos para codificar dos qubits en un solo fotón utilizando los grados de libertad de polarización y camino. En particular, se presenta la reconstrucción  experimental  de qubits de polarización y se propone un montaje experimental para producir estados arbitrarios de camino  y  polarización.
In order to carry more information, quantum applications search for increasing the useful Hilbert space in which to encode information. In this paper, we report our efforts to encode two qubits in one single photon using the polarization and path degrees of freedom. In particular, we report the experimental state reconstruction of polarization qubits and we propose an experimental setup to produce arbitrary states of path and polarization.
