Quantum amplitude amplification and estimation
, 2002
"... Abstract. Consider a Boolean function χ: X → {0, 1} that partitions set X between its good and bad elements, where x is good if χ(x) = 1 and bad otherwise. Consider also a quantum algorithm A such that A0 〉 = � x∈X αxx 〉 is a quantum superposition of the elements of X, and let a denote the proba ..."

the probability that a good element is produced if A0 〉 is measured. If we repeat the process of running A, measuring the output, and using χ to check the validity of the result, we shall expect to repeat 1/a times on the average before a solution is found. Amplitude amplification is a process that allows
Simplified processing for high spectral efficiency wireless communication employing multielement arrays
 IEEE J. Select. Areas Commun
, 1999
"... Abstract — We investigate robust wireless communication in highscattering propagation environments using multielement antenna arrays (MEA’s) at both transmit and receive sites. A simplified, but highly spectrally efficient space–time communication processing method is presented. The user’s bit str ..."

Of Amplitude Modulation
 J. Acoust. Soc. Am
, 1997
"... This paper presents a quantitative model for describing data from modulationdetection and modulationmasking experiments, which extends the model of the "effective" signal processing of the auditory system described in Dau et al. [J. Acoust. Soc. Am. 99, 36153622 (1996a)]. The new elemen ..."

 Add to MetaCart
element in the present model is a modulation filterbank, which exhibits two domains with different scaling. In the range 010 Hz, the modulation filters have a constant bandwidth of 5 Hz. Between 10 Hz and 1000 Hz a logarithmic scaling with a constant Qvalue of 2 was assumed. To preclude spectral
Full ComplexAmplitude Modulation Diffractive Optical Element
"... Diffractive optical elements (DOE’s) are being used in a increasing number of applications, such as beam shaping, optical interconnects and filtering. Their main advantages over traditional refractive optical elements are: their reduced size and weight, the possibility of being mass fabricated, what ..."

, what reduces their cost, and superior performance in several industrial applications. In order to reduce the design complexity and increase the performance and robustness, a novel, full complexamplitude modulation diffractive optical element was designed. This new element allows the full control over
Quantum Algorithms for Element Distinctness
 SIAM Journal of Computing
, 2001
"... We present several applications of quantum amplitude amplification to finding claws and collisions in ordered or unordered functions. Our algorithms generalize those of Brassard, Høyer, and Tapp, and imply an O(N 3/4 log N) quantum upper bound for the element distinctness problem in the comparison c ..."

"... QCDSF–UKQCD Collaboration Results are presented for the lowest moment of the distribution amplitude for the K ∗ vector meson. Both longitudinal and transverse moments are investigated. We use two flavours of O(a) improved Wilson fermions, together with a nonperturbative renormalisation of the matri ..."
