Extending the single photon transmission distance is a basic requirement for the implementation of quantum communication on a global scale. In this work we report the single photon exchange from a medium Earth orbit satellite (MEO) at more than 7000 km of slant distance to the ground station at the Matera Laser Ranging Observatory. The single photon transmitter was realized by exploiting the corner cube retro-reflectors mounted on the LAGEOS-2 satellite. Long duration of data collection is possible with such altitude, up to 43 minutes in a single passage. The mean number of photons per pulse (µsat) has been limited to 1 for 200 seconds, resulting in an average detection rate of 3.0 counts/s and a signal to noise ratio of 1.5. The feasibility of single photon exchange from MEO satellites paves the way to tests of Quantum Mechanics in moving frames and to global Quantum Information.Introduction -Quantum Communications (QC) are necessary for tests on the foundation of Quantum Physics, such as Bell's inequalities violation [1][2][3], entanglement swapping [4,5] and distribution [6], and quantum teleportation [7]. Moreover, the transmission of light quanta over long distances is crucial for the realization of several Quantum Information protocols, as quantum key distribution (QKD) [8][9][10], quantum authentication [11] and quantum digital signature [12].

-In this paper we present a work of text steganography. Now a days, maintain the security of the secret information has been a great challenge. Sender can send messages habitually through a communication channel like Internet, draws the attention of third parties, hackers and crackers, perhaps causing attempts to break and expose the unusual messages. Steganography is a promising region which is used for secured data transmission over any public media. Substantial amount of research work has been accepted by different researchers on steganography. In this paper, a text steganography procedure has been planned with the help of an Indian regional language i.e. Oriya language. Text steganography together with quantum approach based on the use of two specific characters and two special characters like invited comas (opening and closing) in Oriya language and mapping technique of quantum gate truth table have been used.

-In this contribution we present a work of text steganography. Maintain the security of the secret information has been a great challenge in our day to day life. Sender can send messages habitually through a communication channel like Internet, draws the attention of third parties, hackers and crackers, perhaps causing attempts to break and expose the unusual messages. Steganography is a talented province which is used for secured data transmission over any public media. Extensive amount of research work has been established by different researchers on steganography. In this paper, a text steganography procedure has been designed with the help of a Regional language of India i.e. Gujarati language. Here the quantum approach also incorporates for increasing the security level. A Revised SSCE code (SSCE -Secret Steganography Code for Embedding) has been implemented in this work to upgrade the level of security. Text steganography together with Revised SSCE code & quantum approach based on the use of two specific and two special characters in Gujarati language and mapping technique of quantum gate truth table have been used.
