### Course description

Learn to build quantum algorithms from the ground up with a quantum computer simulated in your browser in this course, created in collaboration with quantum researchers and practitioners from Microsoft, X, and Caltech's IQIM. Quantum computing is an endeavor that's been promised to upend everything from codebreaking, to drug development, to machine learning. With so much hype, it's easy to get lost marveling at the possibilities, without grasping what quantum computing actually is. Our focus is learning how to exploit the laws of quantum mechanics in order to compute. By the end, you'll know your way around the world of quantum information, have experimented with the ins and outs of quantum circuits, and have written your first 100 lines of quantum code — while remaining blissfully ignorant about detailed quantum physics.
