TOCHA in a nutshell

The TOCHA project, funded under the Horizon 2020 EU research and development programme, has the ambition of harnessing topological concepts for future generation of devices and architectures across which information can flow without losses. This conceptually simple yet technologically and fundamentally challenging requirement is crucial for the development of technologies in fields ranging from information processing to quantum communication and metrology. In each of these areas, the dissipation of information is a key hurdle that leads, for example, to unacceptable thermal loads or error rates.

TOCHA will investigate topological protection in novel materials and nanoscopic structures to empower electrons, phonons and photons to flow with little or no dissipation and, ultimately, crosslink them within a hybrid platform. This will entail the design of novel topological photonic/phononic waveguides and the engineering of disruptive heterostructures elaborated from the combination of topological insulators and ferromagnetic materials.

Thanks to its high interdisciplinary embodiment involving electronic materials, optics, thermal management and metrology, TOCHA will help advance all levels of the value chain, from fundamental science to engineering and technology.
