The groundbreaking impact that Quantum Computers (QC) will have on national security, coupled with today's early commercialisation of the technology have increased research secrecy, intellectual property applications and protectionist industrial policies among national stakeholders. These trends could bring supply-chain disruptions, delays in QC development, territorial threats, and obscurity in the ways QCs will be used. Policies that promote international flows of talent, strategic supply-chain protectionism, standard-setting and voluntary codes of conduct could solve this issue.
