SIG 2: Solid State and Quantum Materials, Devices and Systems

A central ambition of SIG2 is to identify and close application gaps that currently limit the deployment of THz technologies. These include the need for compact, efficient and high-power THz emitters, robust detectors, frequency-agile components, high-resolution imaging tools, and scalable manufacturing routes. We also seek to identify and develop new application areas for THz devices where the UK research and industrial communities can provide significant contributions or leadership. Such new areas include THz-driven magnetic switching for magnetic memory, or the control and monitoring of electron beams in large-scale scientific research facilities. By connecting academic advances with industrial requirements and roadmaps, the SIG seeks to accelerate translation into areas such as communications, sensing, metrology, space technologies and quantum-enabled instrumentation. It also aims to engage with companies working in microwave–mmWave photonics, metasurfaces, semiconductor devices and advanced materials.

SIG2 fundamental science remit spans along the development and understanding of spintronic THz emitters, THz quantum cascade lasers, nonlinear and topological materials, 2D and van der Waals systems, and strong-field THz interactions. It also aim to acts as a bridge between the THz community and the UK Quantum Technologies Programme and its community. Solid-state THz platforms play an increasing role in quantum sensing, timing, navigation, chip-scale quantum devices, and potentially quantum-assisted detection.

Exploring activities in advanced THz microscopy, superconducting detector technologies, and emerging topics such as THz-driven accelerator science and high-field THz generation, is also within the scope, with the aim to open new opportunities for UK facilities and international partnerships.

Through targeted meetings, industry-engaged seminars, and showcasing of early-career researchers, SIG2 aims to build a cohesive and outward-looking community driving the next generation of THz solid-state and quantum technologies.
