An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the Internet and in everyday life — for example, at a bank’s ATM.

“I expect that quantum technologies will gradually become integrated with existing devices such as smartphones, allowing us to do things like identify ourselves securely or generate encryption keys,” says Stephanie Wehner, a Principal Investigator at Center for Quantum Technologies at the National University of Singapore (CQT) and co-author on the paper in Nature Communications (open-access arXiv version also available.)

CQT theorists Wehner and Nelly Ng teamed up with researchers at the Institute for Quantum Computing (IQC) at the University of Waterloo, Canada, for the demonstration.
