Why Quantum Computers Were Invented | Richard Feynman Explained

Richard Feynman Explained: Why Quantum Computers Were Invented (Not to Be Faster) | Quantum Computing Explained Simply. Why were quantum computers really built? Not for speed, but because ordinary computers hit a wall trying to simulate nature. Discover the exact number where classical computing breaks, how quantum mechanics really works, and the mystery nobody can explain. In this video, Richard Feynman thinks out loud about the 1981 question that started quantum computing: can a normal computer simulate the quantum world? You’ll see why every extra particle doubles the description, why 300 particles need more numbers than there are atoms in the universe, and why rolling dice can’t fake quantum correlations (Bell’s theorem, explained without math). Then we open up the machine itself: qubits, amplitudes, and interference, the real trick behind quantum algorithms. It doesn’t “try everything at once.” It cancels wrong answers and amplifies the right one, like noise-cancelling headphones for math. We also stay honest about the limits: what quantum computers are actually good for (molecules, materials, chemistry, Shor’s and Grover’s algorithms), what they’re not good for, why they’re so fragile (decoherence and error correction), and what’s still unproven. And at the end, the part nobody understands: what an amplitude really is, and why looking turns a wave into a single result. Topics covered: quantum computing for beginners, Feynman quantum simulation, qubits and superposition, quantum interference, Shor’s algorithm, Grover’s algorithm, Bell’s theorem, quantum measurement problem, decoherence, the future of computing.
