The corona algebra of stablized Jiang-Su algebra

Let $\mathcal{Z}$ be the Jiang-Su algebra and $\mathcal{K}$ the C*-algebra of compact operators on an infinite dimensional separable Hilbert space. We prove that the corona algebra $M(\mathcal{Z}\otimes \mathcal{K})\mathrm{/}\mathcal{Z}\otimes \mathcal{K}$ has real rank zero. We actually prove a more general result.
