Abstract |
Новое направление физики – квантовая информация – возникло на стыке квантовой механики, оптики, теории относительности и программирования, дискретной математики, лазерной физики и спектроскопии и включает в себя вопросы квантовых вычислений, квантовых компьютеров, квантовой телепортации и квантовой криптографии, проблемы декогеренции и спектроскопии одиночных молекул и примесных центров. Сообщается о некоторых новых результатах в этой быстро развивающейся области исследований. |

Abstract |
We describe a heterodyne receiver developed for astronomical applications to operate in the 350 /spl mu/m atmospheric window. The waveguide receiver employs a superconductive NbN phonon-cooled hot-electron bolometer mixer. The double sideband receiver noise temperature closely follows 1 kGHz/sup -1/ across 780-870 GHz, with the intermediate frequency centered at 1.4 GHz. The conversion loss is about 15 dB. The receiver was installed for operation at the University of Arizona/Max Planck Institute for Radio Astronomy Submillimeter Telescope facility. The instrument was successfully used to conduct test observations of a number of celestial sources in a number of astronomically important spectral lines. |
