CERN is preparing one of the biggest upgrades in its history. The Large Hadron Collider is about to increase collision density dramatically — stronger magnets (moving toward 12 Tesla), far more particle interactions, and an explosion in data. The High-Luminosity era will push computing infrastructure to its limits. So 9-year-old Kai went to CERN to ask a direct question: If nature is quantum – and the data is growing beyond anything we’ve handled before – could quantum computers help? Inside CMS, 100 metres underground, protons collide every 25 nanoseconds. Millions of detector channels record events at microscopic precision. Physicists simulate quantum field theory on classical machines — and know exactly where approximations start to strain. This episode covers serious scientific questions emerging from the next phase of high-energy physics.
