New research milestone could solve quantum scalability

 


You cannot dispute the promise of the technology, no matter where you are on the spectrum of quantum skepticism. Don't worry—while we acknowledge that we still don't fully comprehend it, the QuiX Quantum founders do. 

The team has created a wholly integrated quantum light source on a device smaller than a euro coin, working with researchers from the Leibniz University Hannover. 

The research, entitled "Fully on-chip photonic turnkey quantum source for entangled qubit/qudit state generation," was released this week. According to reports, its findings could fundamentally alter technologies like quantum computing. 

Photonics offers temperature advantages

Quantum photonics is a field of study that explores the behavior of light and its interactions with matter at the quantum level. Quantum light sources produce photons that can be used as quantum bits or qubits. One of the main advantages of light quanta over superconducting methods is that it is compatible with operating conditions at room temperature.

However, most sources are external laser systems, making them cumbersome and non-reproducible, and therefore unsuitable for use outside the laboratory or in larger-scale production. Integrated or on-chip sources are gaining popularity because they are more compact and stable. 

A fully integrated light source, such as that demonstrated by scientists from QuiX and Leibniz University, would allow all stages of quantum information processing (QIP) to reside on a single chip. unique, leading to higher technology stability and scalability. 

Plug-and-play photonics solutions

QuiX Quantum was founded in January 2019. Since then, the company has raised more than 5.5 million euros in funding and has become the European market leader in quantum computing hardware. on photonics. It sold its first quantum processor in 2021 and is building €14 million worth of 8 and 64-qubit universal quantum computers for the German Aerospace Center.

The company says its goal is "continuous disruption of quantum computing with high-tech, scalable, scalable, and plug-and-play integrated photonics solutions." we." His recent breakthrough couldn't have come at a better time. The EU has just launched a €19 million project to help quantum startups move from the lab to the market.

Earlier this year, QuiX Quantum won the prestigious Prism Award for its 20-mode quantum photonics processor. The award, known as the "Oscars of Photonics," was presented at the Photonics West conference in San Francisco.

“In four years, we have gone from an idea to delivering award-winning, market-leading hardware for quantum computing,” said Stefan Hengesbach, CEO of Quix. . "This award-winning processor, which is at the core of our current generation quantum computers, has made a huge impact in the quantum ecosystem as a great tool for performing experiments. basic quantum mechanics on chip
