Physics World’s Margaret Harris explains how alien civilizations could be using quantum signals to communicate with us on Earth. This topic is taken from my earlier Physics World article.

Physics World: NIST selects four post-quantum encryption standards
The US National Institute of Standards and Technology (NIST) has selected four algorithms that will be developed as post-quantum encryption standards to protect data from a future quantum computer attack. The announcement follows a six-year competition, with NIST now calling on institutions to investigate how to best apply the standards.
Physics World: Aliens could use quantum signals to communicate with Earth
The Search for Extraterrestrial Intelligence (SETI) might want to add quantum communication to its list of ways for aliens to get in touch. According to calculations by researchers at the University of Edinburgh in the UK, quantum signals would be a viable means of establishing contact across interstellar distances – a result that also suggests we might need to update our technology to recognize any such signals coming in our direction.
