Quantum Computing capabilities will probably delivered through the cloud, as buying quantum computers will not be viable for many organizations in the near future (due to high cost / maintenance effort ). Quantum Computing has many potential uses in Big Data, e.g. in biology but also combinatorics (see e.g. Google's or Microsoft work on this, or search online for "Quantum Algorithm Zoo"). Security claims are mostly related to quantum-based secure communication and key distribution, which are technologies that provably work and are already being transformed into products right now. Breaking security (e.g. by efficient prime factoring) is not of big interest to most researchers, as this is more something that nation states might be interested in. Everyone is aware of the fact that we don't yet have a full understanding of quantum algorithms and the computational power of quantum computers, what's clear though is that classical computers have certain limitations in various domains that can be overcome by quantum computers. What everyone agrees on is that quantum computers will not replace classical computers but will supplement them in certain niches. Not sure if this answers all points, hope it clarifies a bit the motivations behind quantum computing though.
