PLATH Corporation, holding company of the PLATH Group, and Papst Invest invest in future-proof security technology: QuBalt.

Hamburg, February 17, 2021 – With its recent strategic investment in the Hamburg-based company QuBalt GmbH, PLATH Corporation GmbH is strengthening its claim to promote and expand advanced, cutting-edge technology.

Together with the co-investor Papst Invest GmbH & Co. KG and the founders of QuBalt, this creates an ideal set-up for innovative product development and for a successful market launch.

The development of quantum computers by large IT companies is making great progress. It is only a matter of time before the high computing power of quantum computers will make central encryption technologies vulnerable to attacks.

The company QuBalt GmbH has optimized and patented a security technology which is information theoretically secure and subsequently cannot be broken even by quantum computers.

QuBalt’s founders, Wulf Harder and Uwe Resas, have already successfully developed various security systems and are currently working on QuVertex, a quantum-safe system.

Alexander Schaefer, Director Portfolio and Asset Management at PLATH Corporation GmbH, stresses: ‘The QuVertex product will be an ideal extension of the PLATH portfolio, as it can be deployed very usefully in many of the systems we offer. The partners involved complement each other perfectly, as our backgrounds and competencies fit together perfectly.’

Daniel Papst, managing director of Papst Invest GmbH & Co. KG, adds: ‘We are looking forward to combining our licensing know-how with QuBalt’s innovative power and PLATH’s market access – and are very much looking forward to the collaboration.’

Wulf Harder, founder of QuBalt GmbH, explains: ‘With the support of the two new investors, we are gaining extensive know-how and additional approaches for the planned market launch. This allows us to fully concentrate on what we do best: technological innovation.’
