Optimizing state transfer in a three-qubit array via quantum brachistochrone method
Kseniia S. Chernova, Andrei A. Stepanenko, Maxim A. Gorlach
Quantum brachistochrone method has recently emerged as a technique allowing one to implement the desired unitary evolution operator in a physical system within the minimal time. He…
