Quantum Computing

Advances in quantum technologies are starting to move into business applications, with potential impact on computing devices, communications, physical sciences, and society. It’s still early, but big efforts at Google, Microsoft, and IBM (pictured) could pave the way to practical quantum computers. Exponentially more powerful than supercomputers, these systems could exploit fundamental physics to disrupt encryption, A.I., and much of the software world.

Big players: Google, IBM, Microsoft, Intel, Raytheon, D-Wave Systems

Disruptors: Rigetti Computing, IonQ, ID Quantique, Quantum Wave Fund, Quantum Diamond Technologies, QC Ware, 1QBit, Quantum Circuits, Zapata Computing
