Explore the fascinating world of quantum computing in this 47-minute conference talk by Roy van Rijn at Devoxx. Unravel the mysteries of entangled qubits, learn the basics of quantum computing through simple and fun explanations, and witness visual demonstrations using polarization filters and a skippyball nicknamed "Mr Qubit." Discover how to build a working quantum computer simulator in Java and gain insights into larger quantum algorithms, including Shor's Prime Factoring algorithm. Delve into the quantum realm without getting bogged down by complex mathematics, but be prepared for potential feline casualties along the way.
