In this episode of The Quantum Kid, 9-year-old Kai and his science writer mum, Katia Moskvitch, travel to the Atacama Desert in Chile, the driest place on Earth. They visit the Paranal Observatory, home to the Very Large Telescope, which combines four 8.2-meter telescopes into a single virtual mirror, giving it the highest optical resolution in the world. The Atacama is so free of light pollution that astronomical observations are stunning, with the Milky Way stretching overhead like a magical, colorful blanket.With the podcast guests: - Avi Loeb, astrophysicist at Harvard University, and - Karen Hallberg, Nobel Peace Prize laureate and theoretical physicist,they take a look at how quantum technologies and AI could transform space exploration, astronomy, the search for signals of extraterrestrial life - and even our understanding of reality itself. From simulating black holes and the Big Bang to using quantum sensing and quantum communication, Kai asks: can quantum and AI help us answer the biggest question of all — are we alone in the cosmos?In a very down-to-Earth and engaging way, Avi and Karen explain how quantum computing and AI could help scientists process massive amounts of telescope data, explore galaxies, and probe the deepest mysteries of space like dark matter and dark energy. The episode also tackles a big question: could these technologies one day replace human scientists, or are they tools that amplify human curiosity and discovery?Quantum sensors could detect faint gravitational waves or measure tiny changes in space environments with unprecedented precision. Quantum communication may one day link spacecraft across vast distances with ultra-fast, secure signals, while quantum-designed materials may protect astronauts from cosmic radiation on long journeys to Mars and beyond.Watch now on The Quantum Kid YouTube channel: https://www.youtube.com/watch?v=hWrnl0jiZn4Explore other episodes for more fun, educational videos on quantum computing, AI, and their role in the cosmos.#QuantumComputing #AI #QuantumTech #SpaceExploration #Astronomy #Entanglement #QuantumSensors #TheQuantumKid #KaiTheQuantumKid #QuantumPhysics #Innovation #STEM #Learning #LifeLongLearning #Universe #Space

Christmas episode!!In this Christmas episode, Kai - The Quantum Kid - explores what happens when quantum computing meets robotics. With:- John Preskill, Caltech theoretical physicist, who coined the term 'quantum supremacy', and - Ken Goldberg, US Berkley robotics expertwe discuss how quantum computers could help robots make smarter decisions and solve problems faster, and what this could mean for the future of intelligent machines. We also talk about uncertainty - both in the context of quantum and in the context of robotics. Oh, and Kai also teleports to a super cool robotics lab in Zurich, ANYbotics, and meets ANYmal - a robot dog that can walk and climb stairs, and can be go where it's dangerous for humans to go. And, as Kai puts it, 'it's veeeeeryyyy cute!' Quantum computers don’t just calculate faster. They think differently. Could that give robots new abilities? 👇 Now your turn:- How do you think robots might use quantum computers?- What should robots be able to do that they can’t do today?- Would you trust a quantum-powered robot?💬 Leave a comment — Kai reads them and may answer yours in the next episode!👍 If you enjoyed this video, like it so more people can find it🔔 Subscribe to The Quantum Kid for more episodes on quantum computing, coding, AI, and the future of technology👀 New videos coming soon!
In this episode of The Quantum Kid, Katia Moskvitch and nine-year-old co-host Kai explore one of the most fascinating frontiers in modern physics: time travel, and what quantum mechanics and relativity really say about it. Our guest is Scott Aaronson — one of the world’s leading experts in quantum computing, the Schlumberger Centennial Chair of Computer Science at the University of Texas at Austin, and director of UT’s Quantum Information Center.Together, we dig into the science behind the movies — from Back to the Future to Interstellar — and unpack what physics actually allows. Scott explains:- Why traveling forward in time is real physics, not science fiction- What a closed timelike curve is, and why it matters for time travel- How relativity links wormholes and time travel to the past- Why stable wormholes would require negative energy, something never observed- How time-travel paradoxes like the Grandfather Paradox and Shakespeare Paradox challenge our understanding of reality- How quantum superposition and David Deutsch’s 1991 model introduce the idea of branching timelines- Why quantum computers interacting with their past selves would be unimaginably powerful — far beyond anything we expect real quantum computers to doAlong the way, Kai asks what every curious kid wants to know:Can you bring your homework back from the future? Could Marty McFly really fade out of existence? How much of Interstellar is true? And will we ever time-travel for real?To bring the cosmic perspective to life, this episode also features original footage from the ALMA Observatory in the Atacama Desert — one of Earth’s most advanced instruments for exploring the structure of space-time.Whether you're a kid discovering physics for the first time or a researcher wondering how quantum mechanics might resolve time-travel paradoxes, this conversation offers a clear and insightful journey through some of the biggest open questions in science — from wormholes to quantum gravity.Join us, subscribe, and follow along as we continue exploring the universe, one quantum idea at a time.
In this episode of The Quantum Kid, Kai and Katia explore one of the biggest questions of our time: Can quantum computing help the environment and make our world just that tiny bit more sustainable?They’re joined by two legendary scientists: Dr. Steven Chu, Nobel Laureate in Physics and former U.S. Secretary of Energy, and Professor Peter Shor, inventor of Shor’s algorithm, the discovery that sparked the modern era of quantum computing.Together, they discuss how quantum technologies could transform energy systems, climate solutions, and sustainable innovation—and how curiosity and creativity can drive real-world progress.It’s a rare, intergenerational dialogue that connects qubits and climate, mathematics and meaning, and the future of science and the planet—through the eyes of a child and the minds of two of the world’s most visionary physicists.Enjoy the show, spread the word about us, like and subscribe not to miss the future episodes!
In this episode, a 9-year-old codes on a real quantum computer!Join us as we visit an actual quantum computing lab at ETH Zurich - Albert Einstein's alma mater - with Kai, The Quantum Kid. ⭐ And if you haven't yet, don't forget to like and subscribe to our channel! Together, we step inside the cutting-edge world of superconducting qubits and meet Dr Anatoly Kulikov, one of the ETH researchers pushing the limits of physics. And... we even see Kai run his very own quantum algorithm on a live quantum processor!What to expect in this episode: A behind-the-scenes tour of the quantum hardware lab—cryostats, control electronics and all; A engaging, easy-to-follow (for once!) walkthrough of how qubits work and why they can solve certain problems faster than classical computers; Kai executing a simple Qiskit program and watching the results come back from a real quantum computer. Whether you’re completely new to quantum or already working in the field, you’ll get a close-up look at the technology that’s reshaping computing—and the curiosity that drives the next generation of scientists.💡 This podcast is part of Tesseract Quantum’s channel, where you will find more episodes of The Quantum Kid Podcast, as well as our Qubits & Coffee quantum programming webinars, aimed at teaching everyone to program on a quantum computer.And now for those wishing to dive deeper: In this demo, Kai runs what’s called a Rabi experiment on a real quantum computer. Think of a qubit as a tiny arrow that can point anywhere on a ball—this ball is called the Bloch sphere. When we send the qubit a carefully timed “pulse,” the arrow starts to swing back and forth, just like a playground swing.By slowly changing the length of that pulse and measuring where the arrow ends up, we see a beautiful wave pattern in the results—this is the Rabi oscillation. It’s the qubit’s way of showing how it moves between its two possible states.The Bloch sphere is simply the scientist’s map for that motion, letting us picture the qubit’s dance in 3-D space. Seeing the wave appear in the data is proof that the qubit is behaving exactly as quantum physics predicts. Watch the video to see the results!
