Together with their collaborators, Busnaina and Dr. Christopher Wilson, a faculty member at IQC and a professor in the Department of Electrical and Computer Engineering, have realized quantum analog simulation of a new type of system. This version of their simulation, known as the bosonic Kitaev model, is made using a class of subatomic particles called bosons which includes photons (particles of light) and the Higgs Boson, which are linked together in a chain.

NASA’s Cold Atom Lab, a first-of-its-kind facility aboard the International Space Station, has taken another step toward revolutionizing how quantum science can be used in space. Members of the science team measured subtle vibrations of the space station with one of the lab’s onboard tools — the first time ultra-cold atoms have been employed to detect changes in the surrounding environment in space.

An MIT-led group shows how to achieve precise control over the properties of Weyl semimetals and other exotic substances.

A study co-led by Nanyang Asst Prof Chang Guoqing of NTU’s School of Physical and Mathematical Sciences identified two types of van Hove singularities in the topological materials rhodium monosilicide (RhSi) and cobalt monosilicide (CoSi). They found that the van Hove singularities are near the Fermi level – the highest energy level that an electron can occupy at absolute zero temperature. In this situation, it is highly likely that the materials will exhibit desirable quantum properties, such as superconductivity and ferromagnetism.

Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and several collaborating institutions have successfully demonstrated an innovative approach to find breakthrough materials for quantum applications. The approach uses rapid computing methods to predict the properties of hundreds of materials, identifying short lists of the most promising ones. Then, precise fabrication methods are used to make the short-list materials and further evaluate their properties.

In new research published in Nature Synthesis, University of Illinois at Urbana-Champaign bioengineering professor Andrew Smith and postdoctoral researcher Wonseok Lee have developed mercury selenide (HgSe) and mercury cadmium selenide (HgCdSe) nanocrystals that absorb and emit in the infrared, made from already well-developed, visible spectrum cadmium selenide (CdSe) precursors. The new nanocrystal products retained the desired properties of the parent CdSe nanocrystals, including size, shape and uniformity.

To support the expansion of its quantum research activities, The School of Physical and Chemical Sciences at Queen Mary University of London, has installed a dilution refrigerator from Oxford Instruments NanoScience. Since installing the ProteoxMX, the team can perform more experiments at millikelvin temperatures, enabling the research necessary for the development of quantum computing architectures.

An international research team around Marcus Sperling, a START award project leader at the Faculty of Physics, University of Vienna, has sparked interest in the scientific community with pioneering results in quantum physics: In their current study, the researchers reinterpret the Higgs mechanism, which gives elementary particles mass and triggers phase transitions, using the concept of "magnetic quivers."

A major soon-to-begin project aims to develop these critical building blocks to enable future quantum devices. Peter Liljeroth, professor of physics at Aalto University and director of the new Finnish Quantum Flagship, has received a 2,5 million euro grant from the European Research Council for research on quantum materials. The project will start at the turn of the year, and it is hoped to enable technologies that we may not yet even be able to imagine.

Quantum sensor technology promises even more precise measurements of physical quantities. A team led by Christian Roos at the University of Innsbruck has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
