Title: Hyperfine Structure of Transition Metal Defects in SiC
Authors: Benedikt Tissot and Guido Burkard
Abstract summary: We develop a theory for the interaction of an active electron in the $D$-shell of a TM defect in SiC with the TM nuclear spin. Based on our theory we discuss the possibility to exchange the nuclear and electron states with potential applications for nuclear spin manipulation and long-lived nunclear-spin based quantum memories.

Abstract: Transition metal (TM) defects in silicon carbide (SiC) are a promising platform in quantum technology, especially because some TM defects emit in the telecom band. We develop a theory for the interaction of an active electron in the $D$-shell of a TM defect in SiC with the TM nuclear spin and derive the effective hyperfine tensor within the Kramers doublets formed by the spin-orbit coupling. Based on our theory we discuss the possibility to exchange the nuclear and electron states with potential applications for nuclear spin manipulation and long-lived nunclear-spin based quantum memories.

We apply the spin current density functional theory to the quantum spin-Hall phase. We show that the explicit account of spin currents in the electron-electron potential of the SCDFT is key to the appearance of a Dirac cone.

Tin is isoelectronic with silicon, so electrons can easily shuttle from one Sn atom to another to propagate quantum information. A hyperfine-induced electro-nuclear controlled-phase gate operation is predicted to be exceptionally resilient to charge/voltage noise.

Demonstration of electron-nuclear decoupling at a spin clock transition [54.088309058031705]
Clock transitions protect molecular spin qubits from magnetic noise. linear coupling to nuclear degrees of freedom causes a modulation and decay of electronic coherence. An absence of quantum information leakage to the nuclear bath provides opportunities to characterize other decoherence sources.

Hyperfine-mediated transitions between electronic spin-1/2 levels of transition metal defects in SiC [0.0]
Transition metal defects in SiC give rise to localized electronic states that can be optically addressed in the telecom range. For spin-1/2 defects, a combination of the defect symmetry and the strong spin-orbit coupling may restrict the allowed spin transitions. We show via analytical and numerical results that the presence of a central nuclear spin can lead to a non-trivial mixing of electronic spin states.

Chemical tuning of spin clock transitions in molecular monomers based on nuclear spin-free Ni(II) [52.259804540075514]
We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes. The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments. The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.

Transition metal (TM) defects in silicon carbide have favorable spin coherence properties. We model TM defects that have one active electron with spin 1/2 in the atomic $D$ shell. We find that the spin-orbit coupling leads to additional allowed transitions and a modification of the $g$-tensor.

Conditional quantum operation of two exchange-coupled single-donor spin qubits in a MOS-compatible silicon device [48.7576911714538]
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.
