Q.ant has developed a photonic chip process that is able to create highly specialized optical channels on conventional silicon chips. This process will enable today’s established electronic mainframe computers to be equipped with processors that use cutting-edge quantum technology.

“Q.ant developers have succeeded in linking the electronic world to the realm of quantum optics. This new investment is the logical next step on our journey toward developing and fabricating German-made quantum computer chips. Only by taking quick, bold and decisive action now to promote quantum technologies can we ensure that Germany is able to exploit its potential as a major industrial hub and stay ahead of its international competitors,” says Peter Leibinger, chief technology officer at Trumpf. The goal is to develop a fully functional quantum chip in five years or less that will enhance today's computers and make them more powerful

“The various test scenarios we’ve run show that our technology will enable quantum computer chips to be used in conventional computer centers in the future, because they require neither particularly complex cooling nor a vibration-free environment. Our fabrication process is simple compared to that of other quantum computer platforms, and it allows us to generate a large number of quantum bits. Quantum computers need large numbers of these elementary logical units to deliver truly high-performance computing power, so this new process gives us a major competitive advantage on the technology side. We’re currently talking to strategic partners from various industries to get real-world applications in the pipeline as quickly as possible,” says Q.ant CEO Michael Förtsch.

Headquartered in Stuttgart-Vaihingen, the start-up works with chipmakers, IT equipment suppliers and international industrial corporations. Q.ant currently employs 20 people but expects this figure to rise to 120 by the end of next year.

Plans to fabricate chips at Trumpf Photonic Components

The company is also planning further investments in its wholly-owned subsidiary Trumpf Photonic Components, based in Ulm. This is where Q.ant’s quantum computer chips will ultimately be fabricated. Trumpf is already planning to expand the Ulm site’s existing cleanroom fabrication facilities for diode lasers by adding machines and equipment for the fabrication of quantum computer chips.

“As an established manufacturer of components for the semiconductor industry, we offer solid expertise, a strong network of partners and cutting-edge production facilities. That’s the perfect set-up for fabricating quantum computer chips,” says Berthold Schmidt, managing director of Trumpf Photonic Components.

Q.ant is on track to develop chip components for quantum computers by the end of the fiscal year in June 2022. These components will be capable of creating, controlling and manipulating quanta. This is an important step on the path toward creating the first prototype of a quantum computer chip.
