The spin-off company ParityQC has implemented the largest quantum Fourier transform ever reported using an IBM quantum computer, thereby setting a new milestone on the path toward the industrial ...

The Bomem DA3 is a type of Fourier transform spectrometer used for measuring various spectral data and [Usagi Electric] has one. On his quest to understand it he runs down a number of rabbit holes, ...

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

Abstract: The fractional Fourier transform (FRFT) parametrically generalizes the Fourier transform (FT) by a transform order, representing signals in intermediate time-frequency domains. The FRFT has ...

The so-called unit impulse (or mathematical impulse) is of considerable importance in signal theory. This tutorial will examine its physical meaning through an ideal experiment. Note that the delta ...

Researchers have been exploring the theoretical potential of quantum computers for decades. Only in recent years, however, have real systems begun to achieve an accuracy and scale that makes their ...

Programming and reprogramming function-oriented mechanical behaviors of materials is crucial for their adaptivity to varying application scenarios. Different from the methods depending on iterative ...
