CHALLENGE
Help solve a real scientific problem by playing a computer game!
Quantum physicists around the world are trying to build a quantum computer. Such a computer works according to the principles of quantum mechnics and a single quantum computer could potentially be stronger than all conventional computers combined!
But, to build a quantum computer there are still some challenges that need to be solved, and by playing this game you will contribute to this while (hopefully) having fun!
So hurry up and register at the right side of this page! If you are already logged on, go to "Download" in the menu where you will find the newest version of the game.
THE GAME
The game consists of several individual games. Some of these serve as tutorials that will introduce you to the quantum world and in others you contribute to solving the scientific challenges.
The scientific games are marked with a boldface font. In these games you try to solve actual scientific problems. The games are based solely on real physical simulations - no cheating. You are doing front-line research where we do not know the optimal solution. We are axcited to see where our common journey takes us.
The structure of the game will develop as time goes on based upon your feedback, and new games will be created by the players and new features will be introduced according to your suggestions.
THE QUANTUM COMPUTER
The building blocks of regular computers are "bits" that can hold the value 0 or 1. The quantum equivalent is the "qubit" which can hold both 0 and 1 or any combination hereof at the same time. Two qubits can be in any combination of four states (00, 01, 10, and 11) at the same time, and with each addded qubit this number doubles. This exponential growth is extremely fast: just 300 qubits can exist in more states at the same time than the total number of atoms in our universe!
This parallelism in a certain sense allows a quantum computer to perform many calculations at the same time. This is the key feature enabling quantum computer to outperform classical computers for certain tasks.
Qubits can be realized within many different systems - individual atoms, molecules, or ions, photons, or electrical circuits - as long as the particular system obeys the rules of quantum mechanics. In our context we examine an implementation based on the control of individual atoms.

THE CHALLENGE
To build the quantum computer we place one atom (qubit) in each well of an egg tray shaped structure (so-called optical lattice). This has been realized experimentally but to preform quantum calculations we need to be able to pick up individual atoms and move them from one well to another in order to make two atoms interact. Steps towards realizing this have been taken (see LITERATURE ON QUANTUM COMPUTERS).
So, the challenge is to grab the atom with light-tweezers (consisting of a laser beam), and then move the tweezers so that the atom follows in a controlled way - and this is the hard part
Any sudden movement of the tweezers will cause the atomes to slosh around, like water in a glass when moved. This will ultimately result in errors in the quantum calculation!
And this is where YOU enter. Our computer simulation software has not been able to calculate a good way to move the atoms with minimal sloshing, but we hope that gamers with their intrinsically human sense of pattern recognition, their steady (but quick!) hands and their patience will be able to solve this problem, and bring us a big step closer to the realization of a quantum computer.
