From the physics point of view, measurement is a physical process that estimates the quantity of a particular observable or a physical parameter. The science of measurement is called metrology. How to improve the precision in metrology is a central issue in this field, for which many classical approaches have been proposed.

The spurious ZZ interaction between qubits is a common crosstalk phenomenon in superconducting qubit chips, which will cause the frequency of qubits to be affected by the surrounding qubits states, thus reducing the manipulation accuracy of quantum gates. Eliminating ZZ interaction is of great significance to improve the overall fidelity of the chip and the depth of the quantum algorithm.

The 17th Symposium of the Study of the Earth’s Deep Interior (SEDI), a Committee of the International Union of Geodesy and Geophysics (IUGG), was recently held in Zurich, Switzerland.

Recently, scholars from the Southern University of Science and Technology (SUSTech) received accolades at the 19th Annual Meeting of the Asia Oceania Geosciences Society (AOGS2022).

Inspired by the discovery of an S=N bond in the collagen IV network and its essential role in stabilizing basement membranes, sulfilimines have drawn much attention in the fields of chemistry and biology. Derivatization of peptides and proteins with this S(IV)-derived motif could endow them with novel features. However, its further uptake is hindered by the lack of mild, efficient, and environmentally benign protocols by which sulfilimines can be constructed under biomolecule-compatible conditions.

Alkylated aromatics play an important role in medicinal chemistry, materials chemistry, and energy chemistry. Direct alkylation of the C-H bonds of arenes in a selective manner is one of the most important and straightforward ways to synthesize alkylated aromatics.
