This 9-year-old ran his own program on a real quantum computer

In this episode, 9-year-old Kai 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.
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
• An easy-to-follow 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.

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, 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 3D 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!
