New method enables seamless integration of synthetic diamonds into advanced quantum devices and electronics.

Researchers in the University of Chicago and Argonne National Laboratory are working on a new diamond bonding technique which is set to transform quantum electronics. This new process is supposed to allow for the direct bonding of synthetic diamonds directly to materials such as silicon, sapphire, and lithium niobate without using an intermediary substance.

Traditionally, diamonds have been extremely difficult in traditional ways to introduce into electronics, simply because they have a preference for bonding only with other diamonds and possess some unique properties. Using the new approach, which involves surface treatment, the surfaces can be made "sticky," so easily bonding with other materials. This breakthrough now enables the application of ultra-thin diamond membranes of down to 100 nanometers, while at the same time retaining all important spin coherence for potential quantum applications.

This development is of huge importance to the fields of quantum computing and sensing technologies, in which material quality and integration play a central role. The researchers hope that improvement in scalability and efficiency of diamond integration will eventually trigger a CMOS-style revolution in quantum technologies.

Such bonding process is patented, and its commercialization will be done through the Polsky Center for Entrepreneurship and Innovation at the University of Chicago. This may change all methods of manufacturing quantum electronics because it makes processes more efficient and accessible to many applications.
