Provided are an auto-compensating quantum cryptography transceiver and method of transmitting a quantum cryptography key at a high speed. A quantum cryptography transmitter includes a wavelength converter, an optical attenuator, an optical phase modulator, and a Faraday mirror. A quantum cryptography receiver includes a polarization beam splitter, an optical coupler, an optical filter, and a photon detector. Thus, a limit of a transmission rate caused by Rayleigh scattering of an optical fiber can be overcome.

Apparatuses and techniques relating to an augmented reality (AR) device are provided. The device for augmenting a real-world image includes a light source information generating unit that generates light source information for a real-world image captured by a real-world image capturing device based on the location, the time, and the date the real-world image was captured. The light source information includes information on the position of a real-world light source for the real-world image. The device further includes a shadow image registration unit that receives the light source information generated from the light source information generating unit. The shadow image registration unit generates a shadow image of a virtual object overlaid onto the real-world image based on the light source information generated from the light source information generating unit.

There are provided an apparatus for fixing a plastic sheet which fixes a plastic sheet to fabricate a nano pattern and a method of fabricating a nano pattern on a plastic sheet using the same. The apparatus for fixing a plastic sheet includes: a pair of planar metal guide rings interposingly fixing a plastic sheet from above and below, respectively; and a sheet fixing chuck including: a ring fixer sucking the pair of planar metal guide rings through a vacuum groove to be fixed thereto; and a sheet fixer having a plurality of vacuum pin holes formed therein, the vacuum pin holes sucking a bottom of the plastic sheet fixed by the planar metal guide rings. The apparatus allows fabrication of the nano pattern on the plastic sheet having less roughness than that of a semiconductor substrate or a glass substrate.
