Q|Cards> is an educational multiplayer game designed to get familiar with the basics of quantum computing in an interactive and accessible way. No prior knowledge required — just strategy and curiosity! ◆ How to play? Try to flip the quantum state of your qubit-merperson from |0> to |1> by placing cards, while keeping the state of your opponents' as close to |0> as possible. Each card represents a real quantum gate —the operations run on quantum computers. At the end, check the winner via measurement!  ◆ Key features • Multiplayer mode: Play with 2-5 players, choose 2–7 rounds, and hold up to 8 cards in hands • Set your pace: Choose 10s, 1m, or unlimited time to think your next move • Private & public game rooms: Create private rooms, invite friends, or join public games • Card Library: Explore rapid or more detailed built-in descriptions of each quantum gate to learn how they work • Quantum intuition: Learn as you play, or dive deeper into about superposition, entanglement, and quantum measurement in the Wiki sections  • Powered by IBM Quantum: The quantum circuits you build in the game are simulated in the background using the open-source quantum computing library Qiskit  • Download now Q|Cards> and start playing! ◆ Born from passion, built for learning Originally a tabletop card game conceived at the 2019 Quantum Wheel game jam, Q|Cards> has now evolved into a mobile multiplayer experience and been updated as part of the European initiative DigiQ (Digitally Enhanced Master in Quantum Technology).

In 1998, NASA’s Launch Services Program (LSP) was established to support NASA’s science and robotic missions by procuring commercial launch vehicles. The program was established at NASA’s Kennedy Space Center to centralize technical and management support to spacecraft customers. LSP brings together people, procurement, engineering best practices, strategic planning, studies, and cutting-edge techniques—all instrumental components for the United States to have a dependable and secure Earth-to-Space bridge that is dedicated to launching all types of spacecraft. This game goes through the process of a spacecraft matching to a rocket, the integration of the spacecraft to the rocket and the engineering behind it, and its eventual launch into space and the correct orbit. The game consists of 8 mini games to educate the player on the process Features: • Buying a rocket • How to get where you want to go in space • Analyzing the rocket and spacecraft • How to clean a spacecraft • Putting together a rocket • Time to fuel up • Frequency • Staying on target The characters that the player can choose from are represented by animals that are found in the Cape Canaveral Wildlife Refuge which encompasses Kennedy Space Center and Cape Canaveral Space Force Base. • Tortoise • Manatee • Wild hog • Bobcat • Alligator • T- Rex (not found in the Cape Canaveral Wildlife Refuge)
