Neutron scattering measurements on the pyrochlore magnet Ce$_2$Zr$_2$O$_7$reveal an unusual crystal field splitting of its lowest $J$=5/2 multiplet, suchthat its ground state doublet is composed of m$_J$=$\pm$3/2, giving thesedoublets a dipole - octupole (DO) character with local Ising anisotropy. Itsmagnetic susceptibility shows weak antiferromagnetic correlations with$\theta_{CW}$=-0.4(2)K, leading to a naive expectation of an All-In, All-Outordered state at low temperatures. Instead our low energy inelastic neutronscattering measurements show a dynamic quantum spin ice state, with suppressedscattering near |$\textbf{Q}$|=0, and no long range order at low temperatures.This is consistent with recent theory predicting symmetry enriched U(1) quantumspin liquids for such DO doublets decorating the pyrochlore lattice. Finally,we show that disorder, especially oxidation of powder samples, is important inCe$_2$Zr$_2$O$_7$ and could play an important role in the low temperaturebehaviour of this material.
