“…The main finding is that, in the weakly Rashba spinorbit coupling regime, chaos can significantly enhance the spin-orbit entanglement. Because of the potential role of such intra-particle entanglement in, e.g., quantum teleportation and communication, [76,77] our result points at the advantage of exploiting classical chaos in these applications. [25,27] It is worth emphasizing the difference between the present work and our previous works on the role of chaos in spin transport.…”

For a quantum system with multiple degrees of freedom or subspaces, loss of coherence in a certain subspace is intimately related to the enhancement of entanglement between this subspace and another one. We investigate intra-particle entanglement in two-dimensional mesoscopic systems, where an electron has both spin and orbital degrees of freedom and the interaction between them is enabled by Rashba type of spin–orbit coupling. The geometric shape of the scattering region can be adjusted to produce a continuous spectrum of classical dynamics with different degree of chaos. Focusing on the spin degree of freedom in the weak spin–orbit coupling regime, we find that classical chaos can significantly enhance spin–orbit entanglement at the expense of spin coherence. Our finding that classical chaos can be beneficial to intra-particle entanglement may have potential applications such as enhancing the bandwidth of quantum communications.

“…To this end, the system of electrons and photons is of particular interest; information is stored in the electronic states and transferred via photons [17]. It is then expected that the environment in which the electronic states are prepared [18] has drastic effects on the electron-photon entanglement [19]. In this regard, it is worth mentioning that effects of surrounding, when parameterized properly, can result in a quantum phase transition [20][21][22], with potential applications in information processing [23][24][25].…”
