ZDNET's key takeaways Quantum is almost here, but organizations are not ready. Experts urge moving from 128-bit to 256-bit encryption ASAP. Another looming issue: quantum skills. Quantum computing  is making our future brighter. Quantum computing is making our future more perilous. In the spirit of quantum, both states can be true at once.

Powerful systems will execute in hours or minutes what once took years to process, and these advances are coming soon to an enterprise near you. But with that shift comes some powerful security issues.  Not yet enterprise-ready At least two dozen manufacturers "are now commercially offering more than 40 quantum processing units (QPUs), which are the processing hardware for a quantum computer," according to MIT's most recent  Quantum Index Report . In addition, the "quantum-as-a-service model" is enabling wider access to quantum computing resources.  Still, quantum is not quite enterprise-ready, the MIT researchers stated: "While there have been impressive advancements in performance, QPUs do not yet meet the requirements for running large-scale commercial applications such as chemical simulations or cryptanalysis."
