Credit: ©Science China Press The Hubble parameter is one of the central parameters in the modern cosmology. Their values inferred from the late-time observations are systematically higher than those from the early-time measurements by about 10%. This is called the "Hubble tension". To come to a robust conclusion, independent probes with accuracy at percent levels are crucial. With the self-calibration by the theory of general relativity, gravitational waves from compact binary coalescence open a completely novel observational window for Hubble parameter determination. Hence, it can shed some...

(c) Expectation values of logical Pauli operators and state fidelity... view more  Credit: @Science China Press Universal fault-tolerant quantum computing relies on the implementation of quantum error correction. An essential milestone is the achievement of error-corrected logical qubits that genuinely benefit from error correction, outperforming simple physical qubits. Although tremendous efforts have been devoted to demonstrate quantum e...

In particularly, the use of RE luminescent materials for in vitro and in vivo imaging can e...

(c) A magnification... view more  Credit: @Science China Press Synchronization and transients are two fundamental phenomena in nonlinear and complex dynamical systems, and they also emerge ubiquitously in ecology and evolutionary biology. Synchronization is commonly observed in spatially extended ecological systems and is regarded as the dynamical basis for the emergence of ecologi...
