Document Summary

Uses quantum physics to represent and operate on data. While conventional computers handle bits of data either as 0 or 1 but no both: quantum computing can process bits as 0,1, or both simultaneously, it allows to solve business and scientific problems millions of times faster. Presents computing resources so that they can be accessed in ways that are not restricted by configuration. Allows single physical resource to act as multiple resources i. e. run multiple instances of os. Firms off-load peak demand for computing power to remote, large-scale data processing centers. Firms pay only for the computing power they use, as with an electrical utility. Excellent for firms with spiked demand curves caused by seasonal variations in consumer demand: e. g. holiday shopping. Saves firms from purchasing excessive levels of infrastructure. Data permanently stored in remote servers, accessed and updated over the internet by users.
