Not only is Quantum Computing possible (news to me!). You can can access it in the cloud.
The project builds on know-how developed around IBM’s existing cloud computing service: Quantum Experience, which anyone can access for free. That system went online in May 2016 and recently received an upgraded user interface. “Having it up for ten months has taught us a lot,” says physicist Jerry Chow, who leads the quantum-computing laboratory at IBM’s research centre in Yorktown Heights, New York. It has provided a way for researchers around the world to practise building quantum algorithms without access to their own quantum computer. IBM’s overall strategy is to build “a community and an ecosystem” around its technology, Chow says.
