How is research shaping the future of quantum computing?

A gas of cold atoms that behaves like a single particle: this state of matter, known as a “Bose-Einstein condensate,” allows physicists to better understand quantum systems. But to conduct their experiments effectively, scientists need to rely on numerical modeling of the phenomena they wish to observe.

Perhaps another step toward quantum computing: scientists from the joint QUANTIC project team (ENS-PSL, Mines Paris-PSL, CNRS, Inria) have succeeded in creating strong interactions between multiple photons. This major work has been published in the prestigious journal Nature Communications.

Through his IQ-SCALe project, Thomas Debris-Alazard, a researcher with the joint GRACE project team (at the Inria Saclay Center), will test the robustness of cryptographic tools designed to withstand future quantum attacks.

Researcher Omar Fawzi has successfully developed an algorithm for calculating the physical properties of quantum systems. Is this another step toward the use of quantum computers?

At the intersection of physics and computer science, the new PhIQuS team at the Inria Saclay center, in partnership with the Institut Polytechnique de Paris, is breaking new ground in a largely unexplored field: quantum advantages in distributed systems. Researcher Marc-Olivier Renou explains this ambitious scientific challenge.

Quantum computers promise to speed up certain calculations compared to traditional computers. However, does this computing power alone enable their algorithms to improve the mathematical optimization of complex problems, such as multi-objective optimization?

Although quantum internet is still in its infancy, a major step forward has been taken with the generic computing approach developed as part of the European research program “Quantum Internet Alliance.” Here's how it works.

Mathematicians around the world are working on new schemes capable of withstanding future threats, while building on others already considered “secure.” But how can we be sure that these algorithms will truly prove invincible?

Scientists from Alice & Bob and Inria have submitted a new study illustrating the most efficient method to date in terms of hardware for producing magical states on superconducting quantum computers, a crucial step toward achieving practical quantum computing.

Quobly, a pioneer in quantum microelectronics, and Inria, the French national research institute for digital science and technology, announce a strategic partnership to bring together silicon quantum hardware and control software. This alliance aims to build a sovereign value chain by combining software excellence and hardware engineering.
