Quantum, made easy Q is a quantum circuit simulator, drag-and-drop circuit editor, and powerful JavaScript library that runs right here in your web browser. There’s nothing to install and nothing to configure, so jump right in and experiment! Fire up the Q editor , then tap and drag the pieces around to get a feel for how it works. It’s easy to use on both desktop and mobile devices. Made a mistake? Just tap the Undo button. Free and open-source Q is free to use, our code is open-source, and our API is heavily documented. Still a quantum novice? Each page of API documentation includes simple explanations of basic quantum concepts to get you up to speed quickly. This makes Q ideal for the classroom as well as autodidacts at home. Q just might be the most accessible quantum circuit suite in the world. Join our project on GitHub at https://github.com/stewdio/q.js and drop a link to Q’s website https://quantumjavascript.app on social media with the hashtag #Qjs . Let’s make quantum computing accessible! Beginning evaluation for “Red kangaroo”
