Quantum computer: what is quantum computing?

Quantum computing has promised to modify the papers part of traditional computing and powerful computing systems, it is very innovative. You still need a quantum computer, or a dedicated hardware, to make the technology work. A goal developed by Alice & Bob, which has just raised 27 million euros.

Being part of the future of supercomputing and part of computing, quantum technology continues to evolve. In this context, a quantum computer uses phenomena specific to quantum mechanics. Therefore, technology is opposed to devices that exclusively use electricity. In short, a quantum computer aims to perform calculations that are too complex for a conventional computer.

With this in mind, Alice & Bob are developing the first processor as well as an “error-tolerant” quantum computer. The main problem with this technology is the ability of these machines to correct errors that occur during the generation of qubits. Current research shows that it is still very difficult for any machine to remain in the quantum state. Disruptions, even small, will cause errors, thus distorting the slightest calculations.

That is why the company created by Raphaël Lescanne and Théau Peronnin aims to create a “fully protected” qubit capable of correcting these errors. To achieve this, managers recently demonstrated that their products were able to remain stable for several minutes in one of two errors (compared to a few milliseconds of the rest of the competition).

A “Bell Labs” in quantitative mode

In order to conduct its own research, the company has therefore raised 27 million euros from Elaia, Bpifrance (via the Digital Ventures Fund), Supernova Invest and Breega. The Roundtable aims to accelerate and double the size of the team (currently 40 employees) and maintain a firmly oriented roadmap towards research and development. As for the first machines, they should be delivered in 2026.

Alice and Bob are still a research company. A kind of Bell Labs, which in the next eighteen months will be fully capable of offering an all-error-corrected constant quantum bit‘, says Théau Peronnin, researcher and co-founder of the company. The company’s roadmap is now able to fix the second type of qubit error.

The strategy of this type of company is to produce robust bug-proof qubits. To achieve this, the company applies optimal control engineering designs to obtain hypothetically stable quantum systems. ” Currently, there is no quantum computer to replace traditional equipment, and our ambition is to produce superconductors with perfect controls. In short, we sell computing power by getting our hands on the entire hardware chain. We work from start to finish, from design to machine operations‘ explains the director.

Quantum computers: for which markets?

If, for the time being, the topic is particularly present in the field of research, then the business uses are already in place. According to McKinsey’s estimates, the market is worth several hundred billion dollars in the next five or even ten years. The markets mainly concerned with quantum computers are related to high-dimensional optimization. Thus one naturally thinks of flight chains, engineering evolving by solving systems of equations related to fluid mechanics or even neural learning networks of artificial intelligence.

Another particularly important use, a quantum computer has a unique ability to mimic the action of proteins. ” It represents a profound paradigm shift, like the discovery of penicillin, as well as a technological and sovereign issue.Adds Theo Perronen.

However, quantum techniques should replace classical computation methods within 5-7 years. It should enable the development of relevant use cases by means of training machines. The latter is intended to encode new problems. Or even to analyze the effect of these same machines to validate economic models or not.

There really is a skill shortage

The development of quantum technologies goes hand in hand with having people to move them. Provided you have the necessary skills. ” We have a shortage of skills. It is necessary to recruit people who can fit the topic. Companies should increase the skills of their teams in this topic. Otherwise, the ‘first come first served’ rule will apply. Professionals who have taken a proactive approach will have certain competitive advantages that will greatly encourage innovation‘ says Theo Pironen.

It is therefore expected that technology will first and foremost enter certain niche markets. This will allow the emergence of new uses. Once the possibility of a quantum computer is demonstrated, further announcements should occur in the direction of its development. So it is up to the companies to train their employees on this subject. Otherwise, to recruit experienced researchers in this specialty.

Quantum: “Land of All Illusions”

While the presence of technological biases is an obstacle to the development of artificial intelligence, a quantum computer does not suffer from the same evils. However, the quantum can cause some nonsense.

Quantum is the land of all illusions. Popular culture has used it to manipulate entire sectors of modern science fiction. While it is a very straightforward mathematical representation of things. So it can be difficult, for an uninformed audience, to sort out the fiction and reality of the machines. We are now in a real hardware race. Illusions no longer have any reason to stay‘ the director joked.
