Quantum computing is a vast and complex field encompassing numerous technologies that can be very different from one another. At EURODECISION, we implement decision mathematics algorithms to solve our clients’ business challenges. This requires thorough knowledge of all possible technologies: we therefore conduct ongoing monitoring of the state of the art, particularly in quantum computing.
As part of this work, I wanted to understand the physical functioning of the different available quantum machines and the algorithms they can solve.
Before exploring the various companies commercialising quantum computers, I offer an introduction that will provide you with some basic concepts to get off on the right foot in quantum computing.
For each technology, you will find below an article that briefly explains the physics behind the machine and an example of a problem that can be addressed with it.
- Explanation of how PASQAL computers work, a French start-up that manufactures neutral atom-based quantum simulators, illustrated by an algorithm for solving the travelling salesperson problem (TSP). Read the article
- Explanation of how IBM computers work, a leader and historical player in digital quantum computer design, illustrated by a quantum circuit optimisation algorithm for these machines. Read the article
- Explanation of how computers from French start-up QUANDELA work and Shor’s algorithm. Read the article
- Explanation of an example of a quantum error correction code: quantum processors introduce errors in problem solving that we attempt to minimise and correct with surface codes. Read the article
- Description of quantum networks (parallel computing and quantum internet): How to move from a computer too small to have industrial relevance to a coherent computer? How to secure our communications? Read the article
- Additional articles will be published soon.
I also invite you to discover the summary of my discussions with representatives from several start-ups present at the Big Data & AI Paris 2023 exhibition: Multiverse Computing, Quantum Delft, Alice & Bob, and Qilimanjaro. Read the article
