- Innovative Quantum Method: Researchers at the University of Warsaw have developed a groundbreaking method using quantum memory to perform the fractional Fourier Transform of optical pulses. This experimental implementation opens up new possibilities for designing spectral-temporal filters, enhancing spectroscopy, and improving telecommunications.
-
Time and Frequency Lenses: The team utilized time and frequency lenses, analogous to glass lenses, to convert pulse duration into spectral distribution and vice versa. By applying quadratic phases to the signal, they were able to achieve fractional Fourier Transform. These lenses were implemented using a quantum memory based on rubidium atoms cooled to extremely low temperatures.
-
Implications and Future Prospects: The method’s potential applications in telecommunications and optical receivers for advanced networks, including optical satellite links, are promising. The quantum light processor developed at the University of Warsaw allows for efficient exploration and testing of new protocols, making significant strides in quantum light processing.
