Going with the flow: meet the quantum plumbers
These are great times for quantum physics, with burgeoning applications of “quantum 2.0” technology. In this special issue, Mauro Paternostro provides a bird’s eye view of the quantum-technology landscape. James McKenzie looks at where, how much and in what areas private companies are investing, while Farai Mazhandu and Mhlambululi Mafu point out how Africa is set to take advantage of the “second quantum revolution”. Don’t miss either Philip Ball’s feature on “quantum plumbers”, explore the strange “Wigner’s friend” thought experiment, and do try our fun quantum cryptic word search.
