1. A method for transmitting a first pulse train in a quantum communication system, the method performed by an apparatus and comprising:
receiving a random access (RA) preamble from another apparatus;
transmitting a random access response (RAR) to the another apparatus in response to the RA preamble;
performing a radio resource control (RRC) connection procedure with the another apparatus;
receiving data from the another apparatus; and
decoding the data based on key information,
wherein, based on that the first pulse train is generated in a laser diode of the apparatus and the first pulse train is transmitted from the apparatus to the another apparatus through a quantum channel after respectively passing through a first path and a second path, the key information is determined,
wherein the second path includes N paths,
wherein the N has a value less than or equal to K,
wherein the N and the K are natural numbers, and
wherein K is a maximum number of the second path.
