Abstract:

For quantum communication, quantum multi-user detection must accomplish communication, so that quantum multi-user detection is a key point. In this paper, we note that the quantum multi-user detection differs from the classical one, construct a multi-user quantum communication channel model, and propose a new self-adaptive adjusting quantum detection scheme. This scheme is feasible and error rate is reduced by measuring the actual optical fiber channel.

Key words: quantum communication, channel model, quantum multi-user detection, self-adaptive adjust
