Abstract
We study a doubly discrete quantum sine-Gordon equation, which is deri ved from the quantum Volterra model solved by Faddeev and Volkov [Teor . Mat. Fiz. 92 (1992) 207]. The discrete quantum pendulum is obtained as the simplest special case. The eigenfunctions of its Hamiltonian, d isplayed as densities on the phase space, are very localized around th e classical energy levels.
