摘要：
Quantum key can be theoretically demonstrated to be secure and now commercially available. The bit rate of the quantum key distribution is much lower than that for "one-time pad" needs. The practical bit limitation of the quantum key distribution system is analyzed to explain necessity for bit amplification. The method of bit amplification is also introduced in this paper.
