The scientific community has faced a significant challenge in understanding what drives the complex behaviors, particularly the superconductivity of kagome materials. New research led by Zhenglu Li, assistant professor of materials science at the USC Viterbi School of Engineering, uses a computational approach to unlock the mystery of kagome superconductors, offering unique insights into the way electrons interact with the lattice dynamics.

A groundbreaking study from the Technion-Israel Institute of Technology unveils a newly discovered form of quantum entanglement in the total angular momentum of photons confined in nanoscale structures – just a thousandth the width of a human hair. This discovery could play a key role in the future miniaturization of quantum communication and computing components.

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.

Recently, researchers from the University of Science and Technology of China (USTC) reveals that not all forms of quantum nonlocality guarantee intrinsic randomness. They demonstrated that violating two-input Bell inequalities is both necessary and sufficient for certifying randomness, but this equivalence breaks down in scenarios involving multiple inputs. This finding has been published in Physical Review Letters.

Prof. Liang Jiang and his postdoctoral associate Zhaoyou Wang at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) have developed a new scheme to send quantum information through these transducers. Using their technique, they found they could send a full qubit’s information through a channel, paving the way for hybrid quantum networks. The results were published in Physical Review X.

Yale researchers, in collaboration with scientists from City University of New York, California Institute of Technology, Kansas State University and ETH Zurich, leveraged the unusual properties of phonon-polaritons, a type of quasiparticle, to discover a new way to dissipate the energy of high-speed electrons through the generation of long wavelength infrared light.

he field of spintronics, which integrates the charge and spin properties of electrons to develop electronic devices with enhanced functionality and energy efficiency, has expanded into new applications. Beyond current technologies such as hard disk drive read heads and magnetic random-access memory (MRAM), researchers are now investigating flexible spintronics for use in wearable devices and sheet-type sensors.

Quantum states can only be prepared and observed under highly controlled conditions. A research team from Innsbruck, Austria, has now succeeded in creating so-called hot Schrödinger cat states in a superconducting microwave resonator. The study, recently published in Science Advances, shows that quantum phenomena can also be observed and used in less perfect, warmer conditions.

Scientists at Valis Corporation have demonstrated gravitationally induced wavefunction collapse on an IBM Eagle quantum chip and will present their findings at Deep Tech Week, New York. Their results are consistent with the Penrose-Hameroff theory of Orchestrated Objective Reduction (Orch-OR) – an explanation for human consciousness. The Penrose theory is one of the many competing proposals that solve the famous physics paradox of Schrödinger's Cat.

An invention from Twente improves the quality of light particles (photons) to such an extent that building quantum computers based on light becomes cheaper and more practical. The researchers published their research in the scientific journal Physical Review Applied. "This technology is an essential part of any future photonic quantum computer."
