This is Unesco's International Year of Quantum Science and Technology, marking a century and more since this fascinating branch of physics came to transform our understanding of the world. Not only that, for people of faith quantum science has arguably transformed our understanding of the nature of God and the nature of humanity. Rosa Hunt investigates the strange, and sometimes downright weird world of quantum uncertainty, dead-and-alive cats, and the possibility of multiverses.

Her guests include Professor David Wilkinson, Dr Emily Qureshi-Hurst, Dr Nick Spencer and Father Lee Taylor.
