Recent progresses of terahertz (THz) receivers in China, are reported in this talk. The convenience THz reciever at room-temperature (RT) and high-sensetive superconducting THz recievers at low-temperature are desiged, fabricated and characterized. Nb_5N_6 microbolometer arrays with noise equivalent power (NEP) of 1.7×10^-11 W/Hz^0.5 and 64×64 pixels at 0.65 THz and RT have been constructed. Superconducting hot electron bolometer mixers with noise temperature of better than 8 times of quantum limitation have been obtained at several operating frequencies and 4.2 K. A superconducting hybrid NbTiN-Al kinetic inductance detector with NEP of about 2.6×10^-18 W/Hz^0.5 for phase readout at 4.3 THz and 200 mK has been characterized. Other THz detectors will been discussed also.
