thermodynamic reversibility and unitary crypto gates



I like the last paragraph. It puts into stark perspective, of thermodynamics, the difference between the random walk and the quantum walk. The notion of the random walk “damping” all but the first eigenstate is clear, when seeing how the now-undamped contribution of all the other eigenstates give one “entanglement” states in the quantum walk case.
