Constructing a universal operation scheme for Majorana qubits remains acentral issue for the topological quantum computation. We study theLandau-Zener-St\"{u}ckelberg interference in a Majorana qubit and show thatthis interference can be used to achieve controllable operations. The Majoranaqubit consists of an rf SQUID with a topological nanowire Josephson junctionwhich hosts Majorana bound states. In the SQUID, a magnetic flux pulse candrive the quantum evolution of the Majorana qubit. The qubit experiences twoLandau-Zener transitions when the amplitude of the pulse is tuned around thesuperconducting flux quanta $2e/\hbar$. The Landau-Zener-St\"{u}ckelberginterference between the two transitions rotates the Majorana qubit, with theangle controlled by the time scale of the pulse. This rotation operationimplements a high-speed single-qubit gate on the Majorana qubit, which is anecessary ingredient for the topological quantum computation.
