Little Quantum App vs Q

What is a qubit? How does superposition work? And what is entanglement good for? In the Little Quantum App, Alice and Bob guide you on an accessible journey through the fascinating world of quantum physics. Step by step, you will explore some of the most important concepts of quantum mechanics and discover how ideas that may initially seem abstract can be understood through clear explanations and visual representations. The app combines short, educational animations with interactive elements that help make complex ideas easier to grasp. As you progress through the topics, animations illustrate how quantum states change and how key phenomena of quantum physics arise. After each section, small quizzes allow you to test and deepen your understanding of what you have learned. This combination of explanation, visualization, and interaction makes learning both engaging and effective. The Little Quantum App is the result of a close collaboration between the MCQST Office (Munich Center for Quantum Science and Technology) and the research group of Prof. Steffen Glaser at the Technical University of Munich. The goal of this collaboration is to make fundamental ideas from modern quantum research accessible to a broad audience and to provide an intuitive introduction to the principles of quantum mechanics. At the heart of the app is a special visualization method that represents quantum states as colored spheres. These visual objects are called “qubit beads” and “entanglement beads.” They are based on a mathematical mapping that allows arbitrary quantum states to be displayed in a visual and intuitive way. By observing how the beads move and change, users can develop a clearer understanding of how quantum states evolve. To further support intuitive learning, the digital representations can be complemented by tangible physical models. These hands-on models make it possible to explore quantum concepts not only visually but also spatially. This combination of digital visualization and physical interaction creates a remarkably simple and engaging approach to quantum mechanics. Through this approach, the Little Quantum App opens the door to quantum physics in a playful yet scientifically accurate way. The underlying mathematical structure ensures that the visual explanations remain faithful to the physics while still being easy to understand. The app invites learners to explore the fundamentals of quantum mechanics and discover the ideas behind one of the most exciting fields of modern science.

See a stock's risk as one 0–100 score — and the five numbers behind it. See what you don't know. Most money apps sell confidence: one number, one arrow. Q-Alpha is a learning app that shows you what you don't know. RISK INDEX, SCORE BY SCORE The Risk tab opens with a result already on screen. See how five sub-scores — volatility, momentum, liquidity, trend strength and profitability — make up one 0–100 risk index. Use "Search a symbol" for the built-in assets, or "Paste my data" to get a risk index from your own daily prices and volumes. You get 3 Risk Index lookups a day before you create an account. Prices for the built-in assets come from a demo price path, not live quotes, and every result says so in its "Data source" row. If an asset isn't supported, Q-Alpha says so instead of showing a made-up score. YOUR HOLDINGS, EACH WITH A SCORE Tap "Save to portfolio" under a result, and the Portfolio tab lists each holding with its own risk score — up to 50 holdings on the Free plan, 500 with Pro. SCENARIO REVEAL Lock in your guess for an asset, then see 50 equally likely outcomes laid out as a distribution, with the 80% likely range spelled out. It is computed on your device from the price and volatility you choose, with no direction assumed — not a forecast, just the spread your own assumptions imply. Report what actually happened, and your calibration score shows whether your ranges ran too narrow: a quiet cure for overconfidence. A SIGNAL THAT SHOWS ITS RULE The risk signal applies one published rule to the risk index and writes out its reasoning, so you can see exactly why it says what it says. It is not a forecast and never a buy or sell call. COMPARE AND BALANCE Overlay two assets on the same five-axis radar to see where their risks differ, and run a classical mean-variance allocation on the holdings you track to see how the weights shift. Every result shows its method and data source — an exercise, not a recommendation. QUANTUM ENGINE — A LEARNING DEMO Curious how quantum algorithms work? Run a small QAOA portfolio-selection example, compared side by side with the exact answer and a random baseline, plus a quantum-circuit sampling demo. Both run on a classical simulator: not a quantum computer, not hardware randomness, and never a forecast. PRICED TO LEARN Start free with the Risk Index — on sample data or your own, with 3 lookups a day even before you create an account — and up to 50 portfolio holdings. Pro unlocks Scenario Reveal, the risk signal, the Quantum Engine demo, side-by-side comparison, portfolio optimization and market scan, with up to 500 holdings, for $9.99/month or $59.99/year. One purchase covers iPhone, iPad and Mac. App Store category: Education. Q-Alpha is not investment advice, recommends no product and guarantees no return. Every output is a learning scenario; every decision is yours.
