Pit yourself against atomic physics in Bond Breaker, a new puzzle game based on real nano-scale science. You start this game in the smallest way possible - as a single proton, without even a single atom to call your own. But with a little luck, and a lot of physical chemistry, you'll grow into an atoms, smash together into molecules, or break apart again using lasers, tunneling microscopes, and heat. Created by TestTubeGames and scientists at the CaSTL research center at UC Irvine, this is truly the most accurate physics engine to date. After all, what other game is correct down to the atomic level? When you make and break molecular bonds, you’ll encounter real forces and real physics. This isn’t just simple stuff, either! You'll learn about... The forces that bind molecules together How lasers can excite atoms Why water sticks together into drops What happens when you heat something up And much, much more. Simply put, this is the most fun you can have without buying your own Scanning Tunneling Microscope!

This is not just any puzzle game. This is a quantum puzzle game! You can just play it for fun, or you can use it to conduct scientific research in the field of quantum error correction. These are the puzzles that need to be solved to keep quantum computers free of errors. We need to work out the best way to do it. By becoming a master at this game, you could help build a real-life quantum computer. Check out our website for more details on the science behind the game. This app was developed by Dr James Wootton, a quantum error correction researcher at the University of Basel. It is supported by the NCCR QSIT.
