Abstract: A method of detecting a signal in a wireless communication system supporting multiple-input multiple-output (MIMO) is provided. The method includes obtaining a MIMO channel matrix between a transmission end and a reception end and a reception vector received by the reception end, identifying a modulation scheme of the transmission end, applying a preset equation modification scheme to the MIMO channel matrix and the reception vector according to the identified modulation scheme, and detecting a transmission vector of the transmission end by performing quantum calculation on the modified MIMO channel matrix and the modified reception vector.
