Quantum computing may one day force a rethink of how we rank influential inventions and innovations. This article offers a brief introduction to the core principles behind quantum computing technology, then outlines how to make your existing workforce the catalyst for the crucial experimentation phase that organizations must embrace in order to not get left behind. Although significant engineering challenges must be overcome before quantum computers become a commercial reality, building capabilities early is critical. The authors suggest starting the quantum capabilities journey by filling four key roles. This includes, first, a use-case manager, who can act as an interface between technologists and business units. Second, it includes a quantum data scientist, who can utilize quantum algorithms and quantum computing infrastructure to arrive at valuable and actionable business insights. Third, the team should include a quantum software developer, who can make applications usable, maintainable, and modular. Fourth, an executive sponsor can make a compelling case to the rest of the leadership team for the investment that quantum computing requires.

Quantum computers can solve problems exponentially faster than classical computers can. They will bring about two huge changes: an end to our current infrastructure for cybersecurity over public networks and an explosion of algorithmic power that holds the promise to reshape our world. Scientists face myriad challenges in developing commercially relevant quantum computers. But once they are overcome, the disruption caused by postquantum cryptography will eclipse that of Y2K, which cost the United States and its businesses more than $100 billion to mitigate. This article examines the way quantum computers will not only upend digital security but spur investment, reshape industries, and spark innovation.
