The correlated errors in superconducting qubits have been linked to high-energy particle impacts from cosmic rays, but a direct observation has been lacking. Here, the authors measure the quasiparticle bursts and correlated errors and separate the contributions of cosmic-ray muons and γ-rays in a 63-qubit processor.

Last year we introduced Project Astra, our research prototype of a universal AI assistant. Since then we’ve improved memory, added computer control and enhanced voice output, and are working to bring these new capabilities to Gemini Live and other products.

Swabs from China’s Tiangong space station reveal traces of a bacterium unseen on Earth, with characteristics that may help it function under stressful environmental conditions hundreds of kilometers above the planet’s surface.

Naming their discovery after the station, researchers from the Shenzhou Space Biotechnology Group and the Beijing Institute of Spacecraft System Engineering say the study of Niallia tiangongensis and similar species could be “essential” in protecting astronaut health and spacecraft functionality over long missions.

The swabs were taken from a cabin on board the space station in May 2023 by the Shenzhou-15 crew as part of one of two surveys by the China Space Station Habitation Area Microbiome Programme.

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now discovered that in certain materials it is not only preserved but can even be actively controlled. This is due to a property of the crystal structure called chirality, which also influences many other processes in nature.

The discovery has the potential to lead to a new class of electronic components capable of transmitting information with exceptional robustness and energy efficiency.

From electronics to spintronics, and now to orbitronics: In classical electronics, it is primarily the charge of the electron that counts. In modern approaches such as and spintronics, the focus has shifted to the electron’s spin.
