2、ng which were jointly carried out by subject-matter specialists and patent knowledge experts at the European Patent Office(EPO).The objective of this report is to provide an overview of important patent trends in the field of quantum computing and the following sub-sectors:“physical realisations of

3、quantum computing”,“quantum error correction/mitigation”,and“quantum computing and artificial intelligence/machine learning”.For this study,publicly available patent information based on the EPOs databases for worldwide patent data was analysed.Patent information constitutes a very rich source of te

4、chnical information on inventions for which patent protection was sought based on commercial expectations of the applicants.Patent information often includes technical and other information that is not available from any other source.This report may be helpful as a source of information in the area

5、of quantum computing.The methodology on which this report is based can be used freely,i.e.everyone can adapt the chosen search and analysis approach to their needs,for example to follow trends and developments in other established or emerging technical fields.The increase in the number of inventions

6、 in the field of quantum computing has developed dynamically in recent years.The number of inventions in that field multiplied over the last 10 years,which is well above the generally observed increase in all fields of technology.The figure on the next page shows the number so-called International P
