In almost everything we do, we use the Internet. We live in the internet. Immense quantities of information are uploaded and downloaded over this digital ocean, and the content is very much our own, for now we are all commentators, publishers, and creators. A key issue surrounding Internet use is privacy and security. Today’s Internet is a playground for hackers. From insecure communication links to inadequately guarded private, business and financial data, vulnerabilities are everywhere. A quantum internet based on the laws of quantum physics aims at sinking these troubles down deep to the bottom.
