Superconducting Single-Photon and Photon Number-Resolved Counters

The research of Aleksandr Verevkin focuses in part on the development of state-of-the-art superconducting single-photon counters, suitable for use in photon number-resolved mode with timing resolution in the picosecond range. These detectors can be easily coupled with standard fiber-optical cable and, with proper readout electronics, function as a single-photon counter with negligibly low dark counts and extremely fast response. Such detectors are urgently needed for ultrafast and long-distance optical communications, remote sensing, biophotonics, and quantum information processing.

Consequently, the development of coding methods and signal processing techniques that can fully exploit the potential of multi-antenna OFDM systems will make a serious impact on the direction. Weifeng Su’s group has invented a space-frequency code design method for MIMO-OFDM systems that can guarantee reliable data transmissions at high data rates in broadband wireless communications. This is the first coding scheme to guarantee both full rate and full diversity in such communications. Reported in the July 2005 issue of IEEE Transactions on Wireless Communications, this technology has potential applications in the design of the next generation of broadband wireless Left Original 512x512 host image.

Effective Thermal Control in Nanodevices and Nanomaterials

Rapid improvements in the synthesis and processing of novel materials with structure on nanometer-length scales have created a demand for nanomaterials and nanodevices with controllable kinetics of electrons and phonons. In a series of high-level UB EE PROGRAMS publications, Andrei Sergeev and Vladimir Mitin have shown that the consistent quantum description of the electron-phonon energy transfer and transport phenomena should comprehensively consider the interference phenomena and take into account electron screening specific for nanostructures.
