Orthogonal polynomials, quantum walks and the Prouhet-Tarry-Escott problem
Frederico Cançado, Gabriel Coutinho, Thomás Jung Spier
This paper is motivated by the following problem. Define a quantum walk on a positively weighted path (linear chain). Can the weights be tuned so that perfect state transfer occurs…
