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.

A photon detector module designed, assembled and programmed at University of Waterloo’s Institute for Quantum Computing (IQC) launched into space earlier this week aboard a SpaceX flight and will soon arrive at the International Space Station. It will be used for quantum entanglement science experiments as part of the Space Entanglement and Annealing Quantum Experiment (SEAQUE) implemented by an international consortium under leadership from the University of Illinois Urbana-Champaign.

Nu Quantum, the leading quantum entanglement startup, is adopting CERN-born White Rabbit (WR) technology to enable data-centre scale quantum computing networks. WR enables highly precise timing synchronisation which is crucial for developing large-scale quantum networks. Nu Quantum is the first quantum industrial partner to join the WR Collaboration. The Nu Quantum team will also be previewing their Quantum Networking Unit (QNU) at the National Quantum Technology Showcase in London, a technology that will enable multiple quantum computing nodes to be woven together into a distributed quantum computing machine. This approach is essential to scale-out quantum computing and unlock transformative computational power to tackle outstanding challenges in industry and society.

An international research team led by QuTech has demonstrated a network connection between quantum processors over metropolitan distances. Their result marks a key advance from early research networks in the lab towards a future quantum internet. The team developed fully independently operating nodes and integrated these with deployed optical internet fibre, enabling a 25 km quantum link. The researchers published their findings in Science Advances.

Nu Quantum, the quantum entanglement startup, is today announcing that Roland Acra has joined as a Board Advisor.

Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as ‘momentary’ or ‘instantaneous’: An electron orbits the nucleus of an atom – in the next moment it is suddenly ripped out by a flash of light. Two particles collide – in the next moment they are suddenly ‘quantum entangled’.Today, however, the temporal development of such almost ‘instantaneous’ effects can be investigated. Together with research teams from China, TU Wien (Vienna) has developed computer simulations that can be used to simulate ultrafast processes. This makes it possible to find out how quantum entanglement arises on a time scale of attoseconds. The results have now been published in the journal ‘Physical Review Letters’.

A research team has proposed a wind sensing lidar theory based on up-conversion quantum interference and successfully developed a prototype. Their work is published in ACS Photonics. The team was led by Prof. Xue Xianghui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS).

The research by scientists at the University of York could lead to significant improvements in position emission tomography (PET) scans, widely used in diagnosing cancer and Alzheimer's disease.
