A brotherly research duo has discovered that when the Large Hadron Collider (LHC) produces top quarks – the heaviest known fundamental particles – it regularly creates a property known as magic.

Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

Two University of Rhode Island physics professors have been awarded separate $800,000 grants as part of the National Science Foundation’s $39 million program to grow quantum research at institutions of higher education across the U.S.

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and collaborators have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton.

Recently, a team led by the Laboratoire d’Optique Appliquée (CNRS), in collaboration with ICREA Professor at ICFO Jens Biegert and other multiple institutions (Institut für Quantenoptik - Leibniz Universität Hannover, Fraunhofer Institute for Applied Optics and Precision Engineering IOF, Friedrich-Schiller-University Jena), demonstrated the quantum optical properties of high-harmonic generation in semiconductors. The results, appearing in Physical Review X Quantum, align with the previous theoretical predictions about HHG.

Q*Bird is excited to share their recent achievement in securing quantum communications. Q*Bird, in collaboration with SURF and Quantum Delta NL, has successfully installed a multi-user, multipoint-to-multipoint Quantum Key Distribution (QKD) network in Utrecht. This achievement sets a new benchmark for secure communications, addressing the critical need for advanced data protection in the research and education sector.

A research team led by Professor Jaedong Lee from the Department of Chemical Physics of DGIST (President Kunwoo Lee) has introduced a novel quantum state and a pioneering mechanism for extracting and controlling quantum information using exciton and Floquet states. Collaborating with Professor Noejung Park from UNIST’s Department of Physics (President Chongrae Park), the team has, for the first time, demonstrated the formation and synthesis process of exciton and Floquet states, which arise from light-matter interactions in two-dimensional semiconductors. This study captures quantum information in real-time as it unfolds through entanglement, offering valuable insights into the exciton formation process in these materials, thereby advancing quantum information technology.

The material, based on a framework of ruthenium, fulfils the requirements of the ‘Kitaev quantum spin liquid state’ - an elusive phenomenon that scientists have been trying to understand for decades. Published in Nature Communications the study, by scientists at the University of Birmingham, offers an important step towards achieving and controlling quantum materials with sought-after new properties that do not follow classical laws of physics.

A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light particles). This achievement is expected to enhance the global competitiveness of the team in quantum computation research. Electronics and Telecommunications Research Institute (ETRI) announced that they have developed a system capable of controlling eight photons using a photonic integrated-circuit chip. With this system, they can explore various quantum phenomena, such as multipartite entanglement resulting from the interaction of the photons.

For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists at the Max-Planck-Institute for the Science of Light (MPL) have now demonstrated a particularly efficient way in which photons can be entangled with acoustic phonons. The researchers were able to demonstrate that this entanglement is resilient to external noise, the usual pitfall of any quantum technology to date. They published their research in Physical Review Letters.
