Free-space quantum key distribution (QKD) is being developed for achieving unconditional secure communication over ultra-long distance, which requires higher electronics performance, such as higher time measurement precision, higher data-transfer rate, and higher system integration density. As part of the ground station of the Quantum Science Satellite that will be launched in 2016, we specifically...
Since the 1990s, there has been a dramatic interest in quantum communication. Quantum communication has become the hotspot of future information technology research because of its unique advantages in improving the security, capability and efficiency of information transmission. Free space quantum communication is being developed to ultra-long-distance satelliteto- ground quantum experiment, which...
