Raman Choudhary is a PhD student contributor to Physics World, studying quantum physics in a joint programme by the universities of Minho, Aveiro and Porto, in Portugal. Academically, he is interested in the connections between the foundations and applications of quantum theory. He is also keen on learning skills that help him to think and write well. Outside academia, Raman practises Brazilian jiu-jitsu, Ultimate frisbee and volleyball. He grew up playing cricket in India, and takes every opportunity to watch the Indian cricket team play.
