WebOct 5, 2024 · We show that every Hadamard matrix of size has quantum symmetries and that all Hadamard matrices of a fixed size are mutually quantum isomorphic. These results pass also to the corresponding Hadamard graphs. We also define quantum Hadamard matrices acting on quantum spaces and bring an example thereof over matrix algebras. The Hadamard transform is used extensively in quantum computing.
