The Hadamard transform is a mathematical operation used in various fields, including quantum computing, signal processing, and information theory. It is a specific kind of unitary transformation that takes an input vector and transforms it into another vector of the same dimension. The Hadamard transform is particularly useful because it creates superposition states in quantum computing and can be implemented efficiently.
