Naval Postgraduate School (NPS) physicists are on track to bring the institution’s new atomic fountain online – the largest of its kind in the world – for applications to quantum sensing experiments in precise navigation and timekeeping.

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG), as reported by scientists from Tokyo Tech. The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.

Research teams led by Prof. PAN Jianwei, LU Chaoyang, HU Yongheng, and others have realized a high-performance single-photon source with an efficiency beyond the scalable linear optical quantum computing loss tolerance threshold for the first time, and the comprehensive indicators have reached the international advanced level. The results were published in Nature Photonics on February 28th.

Researchers at the CUNY ASRC and at Florida International University report in the journal Science their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits. Based on this approach, they outline opportunities that advance fundamental understanding of wave-matter interactions and usher wave-based technologies into a new era.

A new study led by Associate Professor Dong Zhaogang from the Singapore University of Technology and Design (SUTD) has found a way to achieve substantial wavelength tuning at ambient conditions using tiny, tunable nanostructures and low-voltage electrical control. This discovery is published in Advanced Materials in a paper titled, “Electrically tunable and modulated perovskite quantum emitters via surface-enhanced Landau damping”.

ICFO researchers, in an international collaboration, have used terahertz light to explore exotic phenomena within magic-angle twisted bilayer graphene. This approach reveals previously unseen behaviors and provides direct insights into the quantum geometry of electronic wavefunctions —the fundamental framework underlying these phenomena.

The University of Oxford research group led by OQC CSO Dr. Peter Leek today announced research demonstrating a fundamental speedup of the controlled-Z gate in superconducting qubits reaching a fidelity of 99.8% in only 25 ns.

For the first time, researchers have demonstrated that phosphorene nanoribbons (PNRs) exhibit both magnetic and semiconducting properties at room temperature. The research, led by the University of Cambridge with international colleagues, establishes PNRs as a unique class of low-dimensional materials that challenges conventional views on magnetic semiconductors, and could provide a stepping stone to unlocking new quantum technologies.

A first-ever discovery of Bose-Einstein condensation (BEC) in a two-magnon bound state has been achieved by a collaborative research team from Southern University of Science and Technology, Zhejiang University, Renmin University of China, and the Australian Nuclear Science and Technology Organization.

A new study from the University of Eastern Finland (UEF) explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable quantum optical phenomena which may enhance quantum technology and paves the road for an exciting nascent field: four-dimensional quantum optics.
