Katia Moskvitch joins Hamish Johnston to discuss The Quantum Kid, the video channel she co-hosts with her son Kai. Their child-led interviews and laboratory visits encourage researchers to explain quantum ideas to wider audiences. The conversation examines whether early exposure to counterintuitive concepts can inspire future science study and participation in quantum technology. The episode is supported by American Elements.
