Quantum Computing Revolutionized: From Schrödinger's Cat to Q-Silicon

Students at the University of Warsaw have developed a method using quantum memory to perform the fractional Fourier Transform of optical pulses, a unique achievement on a global scale. This transformation is useful in designing spectral-temporal filters for noise elimination and improving precision in distinguishing pulses of different frequencies. The researchers used a quantum memory based on rubidium atoms and implemented time and frequency lenses to perform the transformation. The method has potential applications in telecommunications and spectroscopy, but further mapping to different wavelengths and parameter ranges is needed.
