Quantum Computing for Business Leaders

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.
