Chips for quantum processors are to be produced in small batches in just two years. As a leading quantum technology company, Qant contributes its know-how in quantum computer chip production to the cooperation. In addition, the start-up is contributing machines and process technology in an initial investment worth 14 million euros.

IMS Chips is participating with its existing machinery. Quantum chips are considered central building blocks for quantum processors, which will provide a speed advantage in the future, for example, in the environment of high-performance computing centers. In addition to clean room production with appropriate equipment, IMS Chips also brings experts with experience in industrial-scale manufacturing to the cooperation. In return, the start-up invests in manufacturing capacity and equipment geared toward quantum technologies. For the IMS, which is a foundation of the state of Baden-Württemberg, the cooperation offers the opportunity to advance research and development activities.

In addition to quantum processors, the chips, which operate on the basis of light, are to be used in a wide variety of industries in the future: The fields of application range from medical technology, sensor technology and telecommunications to cryptography, logistics and the financial sector. In contrast to many other quantum computing solutions, which operate at cryogenic temperatures up to -273 °C, the photonic chips are operated at room temperature. This significantly simplifies integration into existing computing architectures. For its chips, Qant relies on a specially developed technology platform with lithium niobate, which is perfectly suited for the photonic approach to quantum computing due to its good electro-optical properties.
