Build your own quantum computer with this game from Google

Don’t understand quantum computing? Don’t panic, quantum professionals step in to put it just a click away.

Quantum computing is a very cool technology. But between qubits, entanglement, superposition, and the rest of the vocabulary associated with this system, you have to stick really hard to understand what’s going on behind the scenes; It is often a question of phenomena not only too abstract for a beginner, but also difficult to generalize.

But it’s still worth looking into, and for good reason; We can already say without an iota of exaggeration that this technology will transform our view of the world, while tangible applications can still be calculated with the fingers of one hand. And to help us see things more clearly, Google has produced Very nice little game.

The quantum world is just a click away

Titled “The Qbit Game”, it is presented as “a fun exploration of building a quantum computer, qbit by qbit”. It allows anyone to learn the ins and outs of quantum computing, even without the slightest knowledge of basic physics. The only requirement is an understanding of the basics of the English language. Because at the moment Qbit is only available in Shakespearean language.

When you get to the page, you immediately meet a qubit. This is the basic unit upon which quantum computing is based; Functionally, they perform somewhat the same role as bits in conventional computing.

The goal is to protect these tiny qubits from attacks by the external environment. It starts with temperature. In fact, these machines operate at temperatures relatively close to absolute zero. Therefore it is necessary to neutralize these aggressors, whom the beloved Qubet watches from the corner of his eye anxiously.

The information is thus allowed to be retained, which is the ultimate goal of the researchers and here it is allowed to increase its score. If we can defend our qubits, we will end up joining new units that must also be protected; And the more of them there were, the more difficult it was to defend them. But it also offers them the possibility to enter a state of quantum entanglement (Quantum entanglement).

Very briefly, this term refers to the creation of a kind of invisible “bridge” connecting two particles. This results in two paired particles, which share properties even when far apart; An observation that led Albert Einstein to drop a phrase that has since gone down in history when he spoke of “terrifying remote work”.

Without going into details, what is important is that this entanglement has the peculiarity of doubling the computing capabilities of a quantum computer. The more qubits entangled in the same quantum processor, the higher the computing capacity.

In the Qubit game, then, the goal is to allow as many qubits as possible to coexist in a state of quantum entanglement while protecting them from temperature. You can then redeem the points generated by these “accounts”; Then it becomes possible to reinvest them in improvements that will increase the overall performance of the system…and so on.

Qubit obviously won’t make you a quantum computing specialist. But at least it has the advantage of helping visualize very simple and often very abstract concepts. In particular, Google hopes that this fun little experiment will inspire some, especially the younger ones, to delve deeper into this aspect My themes are definitely cool, but they’re also pretty scary At first glance.

We need more students to pursue careers in building or operating quantum computersAbi Asfaw, chief education officer for Google Quantum, the division of Google that deals with quantum computing. With this game, the company thus hopes to give a taste of qubits to the young future geniuses of the discipline… and if the general public can learn a bit about these concepts while scrolling, it’s always a good idea to take it!
