There is a remarkable characteristic of photosynthesis in nature, that is, the energy transfer
efficiency is close to 100%. Recently, due to the rapid progress made in the experimental …

The radical-pair mechanism (RPM) was introduced in the 1960s to explain anomalously
large EPR and NMR signals in chemical reactions of organic molecules. It has evolved to …

In realistic metrology, entangled probes are more sensitive to noise, especially for a
correlated environment. The precision of parameter estimation with entangled probes is …

Avian magnetoreception is the capacity for avians to sense the direction of the Earth's
magnetic field. Discovered more than forty years ago, it has attracted intensive studies over …

The underlying chemical and physical mechanism of avian navigation is an important issue
of broad interest. One of the most famous candidates is the radical-pair mechanism, which …

Quantum metrology explores quantum effects to improve the measurement accuracy of
some physical quantities beyond the classical limit. However, due to the interaction between …

Although the radical pair (RP) model is widely accepted for birds' orientation, the physical
mechanism of it is still not fully understood. In this paper we consider the RP model in the …

In recent years, people have been extending the concepts developed in quantum
information science to explore quantum dynamics in biological systems. The existence of …

The radical pair (RP) based compass is considered as one of the principal models of avian
magnetoreception. Different from the conventional approach where the sensitivity of RP …

We propose a strategy to measure weak static magnetic fields with nitrogen-vacancy color
center in diamond. Inspired by avian magnetoreception models, we consider the feasibility …
