“…The feasibility of using quantum cryptography for secure satellite communications was investigated by Hughes et al in 2000 [14]. Recently, laser communication experiments between satellites and OGSs were successfully demonstrated [15][16][17], and similar laser communication terminals are used in the satellite QKD [18][19][20]. However, one of the key techniques in the satellite QKD is the polarization tracking technique because the photon polarization state will be changed according to the satellite movement.…”

Satellite quantum key distribution is a promising technique that overcomes the limited transmission distance in optical-fiber-based systems. The polarization tracking technique is one of the key techniques in the satellite quantum key distribution. With free-space quantum key distribution between an optical ground station and a satellite, the photon polarization state will be changed according to the satellite movement. To enable polarization based quantum key distribution between mobile terminals, we developed a polarization-basis tracking scheme allowing a common frame of reference to be shared. It is possible to orient two platforms along a common axis by detecting the reference optical signal only on the receiver side with no prior information about the transmitter's orientation. We developed a prototype system for free-space quantum key distribution with the polarization-basis tracking scheme. Polarization tracking performance was 0.092• by conducting quantum key distribution experiments over a 1 km free space between two buildings in a Tokyo suburb.

“…This Space-QUEST proposal was submitted within ESA's OA-2004 and was rated as 'outstanding' because of both, a novel and imaginative scientific content and for technological applications of quantum cryptography respectively. We intend to explore the possibilities to send, receive and manipulate single entangled photon pairs using telescopes, reflectors and high-power lasers over a distance of some tens of kilometers up to 100 kilometers experimentally [8], see fig 2. A distance of approx. 10 kilometer would already correspond to one atmospheric equivalent and would thus imply the feasibility of installing a ground to satellite link [6].…”

“…36 The requirements are: size 1.391.170.86 m 3 , mass < 100 kg, and a peak power consumption of < 250 W, respectively. A preliminary design of a satellite-based quantum transceiver (including an entangled photon source, a weak pulse laser sources, single photon detection modules together with two transceiver telescopes) based on state-of-the-art optical communication terminals and adapted to the needs of quantum communication is described in detail in 37 and is currently developed in a collaboration with partners from academia and industry.…”

Fundamental quantum optics test as well as quantum cryptography and quantum teleportation are based on the distribution of single quantum states and quantum entanglement respectively. We will discuss recent experimental achievements in the field of long-distance quantum communication via optical fiber as well as in free-space over a record breaking distance of 144 km. The European Space Agency (ESA) has supported a range of studies in the field of quantum physics and quantuminformation science in space for several years, and consequently a mission proposal Space-QUEST Quantum Entanglement for Space Experiments was submitted to the European Life and Physical Sciences in Space Program. This proposal envisions to perform space-to-ground quantum communication tests from the International Space Station (ISS) and will presented in this article.
