Using a novel type of quantum computer, Martin Ringbauer’s experimental team at the University of Innsbruck, and the theory group led by Christine Muschik at IQC at the University of Waterloo, Canada report in a publication in the journal Nature Physics how they have successfully simulated a complete quantum field theory in more than one spatial dimension.

Researchers based at the University of Cambridge have created a three-state (ternary) molecular switch controlled by light and temperature. Unlike materials such as silicon that switches between two states, the new complex material can act as a solid-state optical switch between three different molecular states. This provides a groundwork for future technologies like optical data storage, photonic circuits and quantum computing.

Rackspace Technology, a leading provider of hybrid, multicloud, and AI technology solutions, today announced, working with Munster Technological University (MTU) to unveil QCloud, Ireland's first quantum cloud computing hub on Amazon Web Services (AWS). This groundbreaking initiative aims to enhance collaborative research and remove barriers to accessing cutting-edge quantum computing technologies.

Quantum researchers from CSIRO, Australia’s national science agency, have demonstrated the potential for quantum computing to significantly improve how we solve complex problems involving large datasets, highlighting the potential of using quantum in areas such as real-time traffic management, agricultural monitoring, healthcare, and energy optimisation.

A research team coordinated by the Department of Physics was able to work on the powerful computers of Google's Quantum Artificial Intelligence Lab to conduct a study on confinement in lattice gauge theory. The results of the study have been published in Nature Physics.
