In the last decades, it has been demonstrated that many animal species orient in the Earth magnetic field. One of the best-studied examples is the use of the geomagnetic field by migratory birds for orientation and navigation. However, the biophysical mechanism underlying animal magnetoreception is still not understood. One theory for magnetoreception in birds invokes the so-called radical-pair...

The electron spin is a very promising candidate for a solid-state qubit [1]. Major experimental breakthroughs have been achieved in recent years using quantum dots formed in semiconductor heterostructures based on GaAs technology [2, 3, 4, 5]. In such devices, the major sources of spin decoherence have been identified as the spin-orbit interaction, coupling the spin to lattice vibrations [6, 7,...
