| Abstract | In this paper, we present our approaches to the development of fiber-coupled superconducting single photon detectors with enhanced photon absorption. For such devices we have measured detection efficiency in wavelength range from 500 to 2000 nm. The best fiber coupled devices exhibit detection efficiency of 44.5% at 1310 nm wavelength and 35.5% at 1550 nm at 10 dark counts per second. | ||||

| Title | The electron-phonon relaxation time in thin superconducting titanium nitride films | Type | Journal Article | ||
| Year | 2013 | Publication | Appl. Phys. Lett. | Abbreviated Journal | Appl. Phys. Lett. |

| Abstract | We report on the direct measurement of the electron-phonon relaxation time, τeph, in disordered TiN films. Measured values of τeph are from 5.5 ns to 88 ns in the 4.2 to 1.7 K temperature range and consistent with a T−3 temperature dependence. The electronic density of states at the Fermi level N0 is estimated from measured material parameters. The presented results confirm that thin TiN films are promising candidate-materials for ultrasensitive superconducting detectors.

| Abstract | Монография посвящена актуальным проблемам физики сверхпроводниковых джозефсоновских кубитов — макроскопических квантовых структур, перспективных элементов квантовых компьютеров. Приведены элементы квантовой механики кубитов, фундаментальные свойства сверхпроводников, физика классических и квантовых джозефсоновских структур. Рассмотрены основные типы сверхпроводниковых кубитов. Изложены результаты экспериментальных и теоретических исследований квантовых когерентных явлений в джозефсоновских кубитах. Рассмотрены спектроскопия энергетичеÂских состояний, осцилляции Раби, эффект Ландау-Зинера, многофотонные переходы в одиночних кубитах и в системах связанных кубитов. Изучено влияние шумов на потоковый кубит и на его классический аналог. Для специалистов в области теоретической и прикладной физики, сверхпроводниковой микроэлектроники, а также аспирантов и студентов физико-технических специальностей. |
