Temperature sensing based on slow light via stimulated Brillouin scattering in M-shaped few-mode fiber
This study investigates temperature sensing based on slow light generation via stimulated Brillouin scattering in an M-shaped few-mode fiber. The temperature-dependent properties of four optical modes (LP01, LP11, LP21, and LP02) over a range from –20 °C to 80 °C are analyzed using the…

A Necessary and Sufficient Criterion for the Separability of Quantum State
Quantum entanglement has been regarded as one of the key physical resources in quantum information sciences. However, the determination of whether a mixed state is entangled or not is generally a hard issue, even for the bipartite system. In this work we propose an operational necessary and…

Reformulating the Quantum Uncertainty Relation
Uncertainty principle is one of the cornerstones of quantum theory. In the literature, there are two types of uncertainty relations, the operator form concerning the variances of physical observables and the entropy form related to entropic quantities. Both these forms are inequalities involving…

Study on plume evolution and influencing factors of reservoir and caprock integrity in CO2 deep saline aquifer storage: A case study of Shenhua CCS project
The plume evolution in long-term CO2 storage can cause changes in formation pore pressure, which may lead to caprock integrity failure in severe cases, posing leakage risks. Current studies on CO2 plume evolution and reservoir/caprock integrity mostly rely on single engineering and geological…

Tight N-observable uncertainty relations and their experimental demonstrations
The uncertainty relation, as one of the fundamental principles of quantum physics, captures the incompatibility of noncommuting observables in the preparation of quantum states. In this work, we derive two strong and universal uncertainty relations for N(N ≥ 2) observables with discrete and bounded…
