Q.ant has developed a prototype quantum chip that can successfully simulate random numbers based on quantum effects. The development was part of a research contract from Bundesdruckerei.
The two companies have been collaborating since 2022 under a research development contract to test the applicability of quantum technologies. As part of this, the first generation of Q.ant chips was built into a processor and a prototype system was developed to simulate random numbers, something that has historically been difficult, and which can be used to encrypt data.
Q.ant uses its own technology platform to make the quantum chips, the central components of which are optical waveguides. These enable the control of light and quantum effects in a highly integrated form, which the company says is a prerequisite for commercialising quantum technologies.
The manufacturing process is based on silicon, upon which very thin layers of lithium niobate are applied and then structured into optical waveguides. Lithium niobate is seen as a possible key to future photonic quantum computing.
The system meets the test criteria of the US National Institute of Standards and Technology (NIST) and could provide a further secure source of random numbers, in addition to conventional physical generators.
Q.ant founder and CEO Michael Förtsch said of the cooperation with Bundesdruckerei: “Public authorities and state-owned companies have a special significance as early adopters of innovative technologies. They promote forward-looking technologies and support young companies in this way. In addition, this helps to build up and establish high technology in Germany.”
Dr. Oliver Muth, Project Manager and Senior Principal Secure Materials and Quantum Systems at Bundesdruckerei is similarly enthused: “As part of the Qu-Gov project funded by the Federal Ministry of Finance BMF, we as Bundesdruckerei are evaluating applications in the federal administration in order to enable the state to deal with quantum technologies in a sovereign manner. We are pleased to have found a competent partner in Q.ant, with whom we can jointly shape quantum computing and quantum communication ‘made in Germany’.”
Visitors to Laser World of Photonics in Munich can find out more about this and Q.ant’s other quantum technologies in Hall A1, at Booth 410.
