Title Photon-counting chirped amplitude modulation lidar using a smart premixing method Type Journal Article
Year 2013 Publication Opt. Lett. Abbreviated Journal Opt. Lett.
Volume 38 Issue 21 Pages 4389-4392
Keywords photon-counting detector, lidar, Geiger mode APD, Geiger mode lidar
Abstract We proposed a new premixing method for photon-counting chirped amplitude modulation lidar (PCCAML). Earlier studies used the counting results of the returned signal detected by a Geiger mode avalanche photodiode detector (Gm-APD) to mix with the reference signal, called the postmixing method. We use an alternative method known as the premixing method, in which the reference signal is used to directly modulate the sampling gate width of the Gm-APD, and the mixing of the returned signal and the reference signal is completed before the Gm-APD. This premixing method is more flexible and may perform better than the postmixing method in terms of signal-to-noise ratio by cutting down a separated mixer commonly used in the postmixing lidar system. Furthermore, this premixing method lowers the demand for the sampling frequency of the Gm-APD. It allows the use of a much wider modulation bandwidth to improve the range accuracy and resolution. To the best of our knowledge, this is the first report to use the premixing method in the PCCAML system, which will benefit future lidar applications.

Title High-efficiency single-photon detectors based on NbN films Type Miscellaneous
Year 2013 Publication Abbreviated Journal
Volume Issue Pages
Keywords SSPD, SNSPD
Abstract We present our resent results in development and testing of Superconducting Single-Photon Detectors (SSPD) with detection efficiencies greater than 85%. High values of obtained results are assigned to proposed design of the detector with integrated resonator structure, including two-layer optical cavity and anti-reflective coating (ARC).

Title Квантовые когерентные явления в джозефсоновских кубитах Type Book Whole
Year 2013 Publication Наукова думка Abbreviated Journal
Volume Issue Pages
Keywords Josephson qubit, quantum computer, Rabi cycle, Landau-Zener effect, multiphoton transitions, single qubits
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 энергетиче­ских 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.
