Enabling efficient computation on fault tolerant quantum computers

CORDIS provides links to public deliverables and publications of HORIZON projects.

Links to deliverables and publications from FP7 projects, as well as links to some specific result types such as dataset and software, are dynamically retrieved from OpenAIRE .

Deliverables

Articles in tech journals or business magazines and participation in main conferences (opens in new window)

"Publication of 2 articles in tech journals or business magazines and/or presentations at conferences:The Company plans to publish at least two articles per year in professional journals. It is intended that the subject of the publication and/or presentation at industrial conferences will be results and studies of R&D work carried out, presentation of our solution and functionality, and examples of applications. The publications/presentations are intended to increase the interest of the audience of ""Early adopters"". Therefore, articles will be published in titles that are popular with the target audience and the presentations will take place at business and technical conferences related to business use of quantum computing applications. We also aim to participate in 4 international quantum events. Our experience shows that participation in international conferences is a very effective method of acquiring customers and business partners, building a network of contacts, as well as verifying the current state of knowledge and technology of industry players (including competitors)."
