Blockade of phonon hopping in trapped ions in the presence of multiple local phonons

Abstract

Driving an ion at a motional sideband transition induces the Jaynes-Cummings (JC) interaction. This JC interaction creates an anharmonic ladder of JC eigenstates, resulting in the suppression of phonon hopping due to energy conservation. Here, we realize phonon blockade in the presence of multiple local phonons in a trapped-ion chain. This work constitutes a concrete study on the evolution of multiple local phonons with or without phonon blockade.
