Abstract

Hundred years ago Stern and Gerlach demonstrated that spin-1/2 particles moving through a very high magnetic field gradient showed spin-path entanglement. Here, we show there that one can describe the emergence of the spin state and path variable’s entanglement as a dynamical feature in Stern-Gerlach experiments using open quantum system approach. This novel approach also gives broadening of the spots on the detector as well as the collapse of the wavefunction.
