A new trick brings stability to quantum operations

ETH Zurich
Peer-Reviewed Publication

Quantum exchange or swap gates are an important part of quantum computers with a large number of qubits. Researchers at ETH Zurich have developed a swap gate for qubits made of neutral atoms that is based on a particular physical effect: the state of the particles switches depending on the path they take and is independent of external disturbances. These so-called geometric phases make the system much less susceptible to experimental noise or imperfections. This novel swap gate works with a precision of more than 99,9 percent and can be applied to 17,000 qubits simultaneously.

Optical control of nuclear spins in molecules points to new paths for quantum technologies

Karlsruher Institut für Technologie (KIT)
Peer-Reviewed Publication

Researchers at the Karlsruhe Institute of Technology (KIT) have reported important progress in quantum physics and materials science by optically initializing, controlling, and reading out nuclear spin states in a molecular material for the first time. Because of their weak interaction with the environment, nuclear spins are particularly stable quantum information carriers. The research shows that molecular nuclear spins could be a promising building block for future quantum technologies. The results have been published in Nature Materials.

A high-performance photodetector with precision in structure and power detection

Tokyo University of Agriculture and Technology
Peer-Reviewed Publication

Colloidal semiconductor quantum dots (QDs) are among the most promising materials for optoelectronic device applications. Now, researchers have unveiled a new class of high-performance photodetectors based on QD superlattices, marking a significant advancement in optoelectronics. By precisely organizing semiconductor QDs into ordered architectures, they achieved enhanced charge transport and device efficiency. This breakthrough establishes a clear pathway for next-generation light-detection technologies, with potential applications in imaging, sensing, and advanced photonic systems.

AMOC collapse could turn Southern Ocean into carbon source, adding 0.2°C to global warming

Potsdam Institute for Climate Impact Research (PIK)
Peer-Reviewed Publication

A shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could trigger a substantial release of stored ocean carbon into the atmosphere over hundreds of years, according to a new study that simulated such a collapse under stable climate conditions. This would add 0.2°C of extra global warming. The new paper from researchers at the Potsdam Institute for Climate Impact Research (PIK), published in Nature’s Communications Earth & Environment, highlights the AMOC’s role as a key regulator of the global climate.

Evidence of an exotic atomic nucleus state

GSI Helmholtzzentrum für Schwerionenforschung GmbH
Peer-Reviewed Publication

An international research team has found evidence of the existence of an exotic atomic nucleus state in an experiment at the GSI/FAIR research center in Darmstadt. Although such a state has long been predicted theoretically, it has never been observed before. The system consists of an atomic nucleus of the carbon isotope ¹¹C and an η′ meson (etaprime meson) — a short-lived particle composed of a quark and an antiquark. This system is bound exclusively by the strong interaction, i.e., the force that also holds protons and neutrons together in the atomic nucleus.

Turn enemies into friends: Repurposing the Tip Effect via Magneto-Electric Orchestration

HEP Data Cooperation Journals
Peer-Reviewed Publication

This study proposes a 3D Cu/Fe3O4 Mott-Schottky nano-tip array, which reconstructs the “tip effect” and synergistically integrates electric and magnetic field regulation to achieve uniform lithium deposition, offering an innovative solution for controlling lithium deposition.

S-scheme Sr₂MgSi₂O₇:(Eu,Dy)/CdS heterojunction for round-the-clock photocatalytic H₂ production

HEP Data Cooperation Journals
Peer-Reviewed Publication

In this study, the long-afterglow material Sr₂MgSi₂O₇:(Eu,Dy) was hybridized with semiconductor CdS to fabricate an S-scheme heterojunction, endowing the resultant Sr₂MgSi₂O₇:(Eu,Dy)/CdS catalyst with integrated long-lasting luminescence and photocatalytic performance. The catalyst enables continuous hydrogen production via catalysis under light/dark alternating conditions. This novel strategy sheds new light on the design and development of round-the-clock photocatalysts, and also provides a valuable reference for realizing efficient and stable continuous hydrogen production.
