Abstract
A new era of technology is fast approaching in which quantum computation may be practically realized. In the near future, researchers may require a method of correlating two isolated quantum systems. This would require a signal carrier to be a quantum entity itself. We investigate the quantum states of photons as a medium for encoding information. A communication scheme using the modulation of spatial modes and polarization states in free space or fiber optics is proposed. The Laguerre-Gaussian spatial mode is studied with these applications in mind. We also study photographic slide as a means of creating diffraction gratings. Holographic diffraction gratings were created in order to generate Laguerre-Gauss beam modes of varying quantum number n. The spatial mode phase characteristics were studied with a Mach-Zehnder interferometer.
