Research project Wallenberg Centre for Quantum Technology (WACQT)

WACQT is a national research programme, coordinated from Chalmers, that aims to take Swedish research and industry to the forefront of quantum technology.

The world is on the verge of a quantum technology revolution, with extremely powerful computers, intercept-proof communications and hyper-sensitive measuring instruments in sight. Wallenberg Centre for Quantum Technology is a 12 year SEK 1 billion research effort that aims to take Sweden to the forefront of this very rapidly expanding area of technology. Through an extensive research programme, we aim at developing and securing Swedish expertise within the main areas of quantum technology: quantum computing and simulation, quantum communications and quantum sensing. Our main project is to develop a quantum computer that can solve problems far beyond the reach of the best conventional supercomputers.

WACQT is directed and coordinated from Chalmers University of Technology, however several Swedish universities are involved: KTH Royal Institute of Technology, Lund University, Stockholm University, Linköping University, and University of Gothenburg. The research areas quantum sensing and quantum communication are coordinated from Lund University, KTH Royal Institute of Technology, and Stockholm University. WACQT also has several industrial partner companies.

Non-Hermitian extended midgap states and bound states in the continuum

Maria Zelenayová, PhD student at Fysikum, and her supervisor Professor Emil Bergholtz looked into localization phenomena in non-Hermitian systems that challenge traditional beliefs about states within the energy continuum and those in the gap. The understanding of non-Hermitian extended band gaps and bound states holds significant implications across various domains. In quantum mechanics, this opens up new possibilities for controlling and manipulating the properties of materials. In technology, these insights can be utilized to develop more efficient semiconductors and other advanced materials.
