Why do kids learn quantum faster than adults? John Martinis explains
Why do kids understand quantum concepts faster than adults? Nobel Prize winner John Martinis (2025 Nobel Prize in Physics) and Elisa Torres Durney (founder of Girls in Quantum) join Kai to find out, and to challenge how physics gets taught in the first place.In this episode, we explore why children have a natural advantage with non-intuitive ideas like superposition and entanglement, before anyone's told them physics is supposed to be hard. John shares real advice for parents on how to nurture scientific curiosity through building, playing and asking better questions, not more advanced ones.Chapters:0:00 Meet John Martinis and Elisa Torres Durney2:15 John Martinis on curiosity and building things as a kid6:31 Elisa Torres Durney's path into quantum research9:10 Why the "adult" way of teaching physics is failing14:45 What is quantum chess?

Can quantum computing help unlock fusion energy on Earth?
Why can't we simulate the Sun, and could quantum computers help us build a star on Earth? Watch Kai visit a tokamak to find out.First, though, he heads to the Atacama Desert in Chile, where, among cacti and llamas, two remarkable observatories explore the wonders of the universe. Starting at Paranal and the Atacama Large Millimeter/submillimeter Array (ALMA), Kai ponders how stars shine through nuclear fusion. That question takes him all the way to Japan, to the largest operational fusion reactor in the world, the JT-60SA tokamak, to see how scientists are trying to achieve fusion energy right here on Earth.Back in the studio, MIT physicist Peter Fisher explains why fusion is so difficult, especially when it comes to simulating plasma, where vast numbers of particles interact at extreme speeds. Today's classical computers struggle with this complexity, and that's exactly where quantum computing comes in.Quantum systems could simulate plasma in fundamentally new ways, helping scientists better understand and control fusion reactions. Researchers are already exploring this connection, combining quantum simulations with traditional methods.Chapters:0:00 Why can't we simulate the Sun?0:49 Seeing the invisible: inside Chile's observatories2:32 Inside a real fusion reactor in Japan8:53 How quantum computing could crack fusion17:24 What comes next for fusion energy💬 Leave a comment here on Spotify.

Inside CERN: is quantum computing the answer to the next LHC upgrade?
Kai visited CERN just before the Large Hadron Collider shut down for one of the biggest upgrades in its history.The High-Luminosity LHC will dramatically increase collision density: stronger magnets (up to around 12 tesla), far more particle interactions, and an explosion in data that 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.Chapters:0:00 Introduction to CERN0:21 Particle collision process1:34 Quantum computing role3:35 Inside the CMS experiment5:55 Simulation challenges8:21 Data analysis in control room10:01 Future computing efforts12:05 Global data distribution13:26 Magnet testing and upgradeThis episode covers serious scientific questions emerging from the next phase of high-energy physics.

A kid 3D-printed a human ear — then found out how quantum computers discover new drugs
Would you like to print a new ear? How about a new heart?In this episode of The Quantum Kid, 9-year-old Kai goes somewhere very few kids ever get to go: a real bioprinting lab at ETH Zurich. With the help of a researcher, Kai 3D-prints a mini human ear 🦻 made from living cells, and learns how scientists use printed tissue to study the body and test new medicines.Back in the studio, Kai has a fascinating discussion about another big "wow" in science: the use of quantum computing for drug discovery. He chats with two quantum experts:Pedram Roushan, quantum physicist at Google Quantum AISabrina Maniscalco, Professor of Quantum Information Science and Co-Founder and CEO of AlgorithmiqThey explain how quantum computers are different from regular computers, and why they could help scientists discover new drugs by understanding molecules in much more detail. To help Kai and viewers understand quantum, we use analogies like LEGO bricks with mini brains 🧱🧠: tiny building blocks that can hold lots of possibilities at once, which is exactly what chemistry and biology need.Chapters:0:00 Inside a real bioprinting lab0:20 Why quantum computing matters for medicine0:47 The problem with studying molecules2:42 Why molecules are so hard to simulate6:12 How 3D bioprinting actually works9:25 The challenge of engineering living tissue11:05 The problems classical computers can't solve13:41 Quantum vs. classical computing, explained15:20 How AI and quantum computing work together18:52 What's next for drug discovery20:35 How soon could quantum drug discovery happen?22:22 Inside the design of a quantum algorithm25:01 What the future of science could look likeReal labs.
