• Title: Anisotropy-Exchange Resonance as a Mechanism for Entangled State Switching
• Authors: Eric D. Switzer, Xiao-Guang Zhang, Talat S. Rahman
• Abstract summary: We find that in the case of $S_2,3=1$ particles, the coupled particle entanglement states can be prepared, controlled, and read by the $S_1$ particle. We also find that for particular resonance conditions of the magnetic anisotropy strength $D$ and exchange coupling strength $J$, the entanglement state switching behavior is maximized and is robust against a range of anisotropic application of the exchange coupling.

• Abstract: We explore the three-particle spin model of an $S_{1}=\frac{1}{2}$ particle (e.g. a stationary electron) interacting with two spin-coupled $S_{\text{2,3}}$ particles with exchange coupling and magnetic anisotropy. We find that in the case of $S_{2,3}=1$ particles, the coupled particle entanglement states can be prepared, controlled, and read by the $S_{1}$ particle. We also find that for particular resonance conditions of the magnetic anisotropy strength $D$ and exchange coupling strength $J$, the entanglement state switching behavior is maximized and is robust against a range of anisotropic application of the exchange coupling.

  We show that in the limit one obtains the one-body Hamiltonian for the light particle subject to $N$ (non-local) point interactions placed at fixed positions. We will verify that such non-local point interactions do not exhibit the ultraviolet pathologies that are present in the case of standard local point interactions.

  We explore the control and switching of the entangled spin states of multi-spin particle qubit coupled to an electron. We find that while the onsite magnetic anisotropy in the case of $S_2,3>tfrac12$ allows full control of their spin states via interaction with $S_2,3=tfrac12$, additional mechanisms, such as anisotropic exchange coupling, are required.

  We study multilevel fermions in an optical lattice described by the Hubbard model with on site SU($n$)-symmetric interactions. Raman pulses that address internal spin states modify the atomic dispersion relation and induce spin-orbit coupling.

  We investigate two-hole states in prototypical coupled Si and Ge quantum dots via different theoretical approaches. We find that, in the weak interdot regime, the ground state and first excited multiplet of the two-hole system display -- unlike their electronic counterparts -- a high degree of $J$-mixing. The light-hole component additionally induces $M$-mixing and a weak coupling between spinors characterized by different permutational symmetries.

  Silicon nanoelectronic devices can host single-qubit quantum logic operations with fidelity better than 99.9%. For the spins of an electron bound to a single donor atom, introduced in the silicon by ion implantation, the quantum information can be stored for nearly 1 second. Here we demonstrate the conditional, coherent control of an electron spin qubit in an exchange-coupled pair of $31$P donors implanted in silicon.
