The quantum computing market is a small but rapidly maturing one from the technology perspective. However, for quantum computing to succeed it needs the market in suitable applications to also mature. The quantum computing scientists will tell you: despite the progress the question remains if, not when, quantum computing will become mainstream. This statement on the future for quantum may make it seem as if it is a technology more relevant to a 2050 Trends to Watch than a 2020 one. However, the technology and the application use cases are evolving so fast that Ovum considers it the correct time to shine the spotlight on quantum technology. This Ovum report examines important market trends in quantum computing and offers recommendations for enterprises and vendors. The report includes discussion of use cases, implications for the security area and the interface between classical and quantum computing.
