Pasqal, a Paris-based quantum computing startup, right this moment introduced that it has raised a $100 million Collection B funding spherical let by Singapore’s Temasek. Along with Temasek, current traders Quantonation, the Protection Innovation Fund, Daphni and Eni Subsequent, in addition to new traders European Innovation Council (EIC) Fund, Wa’ed Ventures and Bpifrance (by its Massive Enterprise Fund) additionally participated on this spherical.
What makes Pasqal, which was based in early 2019, stand out in an more and more crowded subject of quantum computing startups is that the corporate is betting on impartial atoms quantum computing. It is a comparatively new and doubtlessly game-changing method to constructing quantum processors. As an alternative of trapped ions (like IonQ) or superconducting quantum computer systems (like IBM), impartial atom quantum processors use lasers to carry atoms in place with what is basically an optical tweezer.
As you possibly can think about, constructing the expertise to carry a single atom — and solely a single atom — on this entice created its personal challenges, however that’s principally a solved drawback now. The benefit right here is that when you are able to do this with tons of of atoms on the identical time, you possibly can create each a really dense matrix of qubits and one which, utilizing holographic strategies, you possibly can reshuffle in 3D area as wanted for a given algorithm. And all of this occurs at room temperature. That nearly makes these machines extra akin to Discipline-Programmable Gate Arrays (FPGAs) than extra conventional quantum processors. Yow will discover a Pasqal’s paper about this course of with extra particulars right here and it’s additionally value noting that Alain Side, who gained a Nobel Prize for his work on quantum entanglement in 2022, is one in all Pasqal’s co-founders.

As Pasqal co-founder and CEO Georges-Olivier Reymond instructed me, the corporate has already demonstrated that it could possibly management greater than 300 atoms at a time. “It’s very laborious to have just one atom in a laser beam and to observe it and to regulate it,” he defined. “However when you obtain that, you possibly can virtually simply scale that and you may create arrays in any form you need.” He famous that the qubits are much like ion-based qubits by way of their coherence time and constancy, but this flexibility and talent to pack these atoms in a really dense array, with solely a few microns between the qubits, may give this expertise a bonus.
Reymond famous that with a few of these fundamental capabilities now in place, the staff is engaged on constructing the quantum management system so it could possibly begin implementing quantum algorithms. And whereas there are startups that concentrate on constructing quantum management {hardware}, none of them are optimized for impartial atoms, he famous, so the corporate determined to construct its personal system.
Clearly, the Pasqal staff is kind of optimistic about its system and Reymond believes that the staff will have the ability to present its potential clients “quantum enterprise benefit” in 2024. He believes that this can take a system with 200 to 300 qubits.
At this level, most researchers consider that we gained’t see the trade development towards a single expertise for fixing each algorithm. As an alternative, totally different quantum applied sciences will discover their candy spots for fixing totally different issues. For Pasqal, the staff believes that its system will work particularly effectively for graph-centric issues. “There are plenty of computational challenges you could reframe within the form of a graph,” he defined. “What we are able to do with atoms, is we are able to signify the form of this graph and embed the complexity of the algorithm on this geometry. Ultimately, as an alternative of utilizing hundreds of quantum gates, simply by implementing a few them, you possibly can run your algorithm after which you’re resilient to errors.”
The corporate is at present working with the likes of Crédit Agricole CIB, BASF, BMW, Siemens, Airbus, Johnson & Johnson and Thales to assist them perceive the place its expertise can resolve their enterprise wants.
“We’re very pleased with this new milestone in PASQAL’s improvement that may make the corporate a world chief,” stated Christophe Jurczak, managing companion at Quantonation. “Quantonation has supported the corporate since its spin-off from Institut d’Optique. It’s the first scale-up inside Quantonation’s portfolio, and it really illustrates the excellence of French analysis and the competitiveness of the French quantum ecosystem.”
