An FPGA Architecture for Extracting Real-Time Zernike Coefficients from Measured Phase Gradients
Measurement Science Review, 2015 Zernike modes are commonly used in adaptive optics systems to represent optical wavefronts. However, real-time calculation of Zernike modes is time consuming due to two factors: the large factorial components in the radial polynomials used to define them

Adiabatic quantum computation with Cooper pairs [PDF]
, 1997 We propose a new variant of the controlled-NOT quantum logic gate based on adiabatic level-crossing dynamics of the q-bits. The gate has a natural implementation in terms of the Cooper pair transport in arrays of small Josephson tunnel junctions.

HEART RATE COMPUTATION IMPLEMENTED ON FIELD PROGRAMMABLE GATE ARRAY BOARD
Techne, 2010 Heart rate is the most basic information of heart activities. This paper aims to describe a possible real time system to detect electrocardiogram (ECG) signal, count the R-R interval of the ECG signal, and compute the heart rate.

Multiband Real-Time Coherent Optical OFDM Reception up to 110 Gb/s with 600-km Transmission
IEEE Photonics Journal, 2010 We demonstrate field-programmable gate array (FPGA)-based multiband orthogonal frequency-division multiplexing (OFDM) signal reception after 600-km standard single-mode fiber (SSMF) transmission and 400-ps differential-group delay (DGD) at 110-Gb/s.

Classical programmability is enough for quantum circuits universality in approximate sense [PDF]
arXiv, 2001 It was shown by M.A. Nielsen and I.L. Chuang 1997, that it is impossible to build strictly universal programmable quantum gate array, that could perform any unitary operation precisely and it was suggested to use probabilistic gate arrays instead. In present work is shown, that if to use more physical and weak condition of universality (suggested ...
