Radio waves form the backbone of modern wireless communication, from mobile phones and Wi‑Fi to satellite links and radar. But when we ask, “how fast are radio waves?”, the answer hinges on where they are travelling. In a perfect vacuum all electromagnetic waves, including radio waves, move at the same universal speed—the speed of light.…

What is the Quantum Fourier Transform? The Quantum Fourier Transform (QFT) is a cornerstone algorithmic tool in quantum computing, enabling the extraction of frequency information from quantum states with remarkable efficiency. In essence, the quantum fourier transform is the quantum analogue of the discrete Fourier transform (DFT) in classical computing, but it operates on quantum…
