Quantum spin networks having engineered geometries and interactions are eagerly pursued for quantum simulation and access to emergent quantum phenomena such as spin liquids. Spin-1/2 centers are particularly desirable, because they readily manifest coherent quantum fluctuations. Here we introduce a controllable spin-1/2 architecture consisting of titanium atoms on a magnesium oxide surface. We tailor the spin interactions by atomic-precision positioning using a scanning tunneling microscope… Expand
Enhanced quantum coherence in exchange coupled spins via singlet-triplet transitions
TLDR
This work engineered the magnetic interactions between the electron spins of two spin-1/2 atoms to create a “clock transition” and thus enhance their spin coherence and demonstrates that atomically precise spin structures can be designed and assembled to yield enhanced quantum coherence. Expand
Probing resonating valence bond states in artificial quantum magnets
TLDR
This work constructed artificial quantum magnets on a surface by using spin-1/2 atoms in a scanning tunneling microscope (STM) to characterize the resulting collective magnetic states and their energy levels, and performs electron spin resonance on individual atoms within each quantum magnet.

Probing quantum coherence in single-atom electron spin resonance
TLDR
This work elucidate and control the interplay of an Fe single spin with its atomic-scale environment by precisely tuning the phase coherence time T2 using the STM tip as a variable electrode, and finds that the decoherence rate is the sum of two main contributions. Expand
Tuning the Exchange Bias on a Single Atom from 1 mT to 10 T.
TLDR
The precise control of the exchange bias experienced by a single atom on a surface is demonstrated, covering an energy range of 4 orders of magnitude, and a time-varying exchange interaction generates a localized ac magnetic field that resonantly drives the surface spin. Expand
Free coherent evolution of a coupled atomic spin system initialized by electron scattering
TLDR
Insight is provided into the locality of electron spin scattering and set the stage for controlled migration of a quantum state through an extended spin lattice by tracing the free coherent evolution of a pair of coupled atomic spins by means of scanning tunneling microscopy. Expand
Tuning Single-Atom Electron Spin Resonance in a Vector-Magnetic Field.
TLDR
It is shown how the ESR amplitude can be greatly improved by optimizing the magnetic fields, and how the stray field from the magnetic STM tip is a versatile tool, which promises to make this technique available in many existing STM systems. Expand
Coherent spin manipulation of individual atoms on a surface
TLDR
By modulating the atomically confined magnetic interaction between the STM tip and surface atoms, this work drives quantum Rabi oscillations between spin-up and spin-down states in as little as ~20 nanoseconds. Expand
Enhanced lifetimes of spin chains coupled to chiral edge states
We consider spin relaxation of finite-size spin chains exchanged coupled with a one dimensional (1D) electron gas at the edge of a Quantum Spin Hall (QSH) insulator. Spin lifetimes can be enhancedExpand
Topological spin excitations in Harper-Heisenberg spin chains
Many-body spin systems represent a paradigmatic platform for the realization of emergent states of matter in a strongly interacting regime. Spin models are commonly studied in one-dimensionalExpand
Creating designer quantum states of matter atom-by-atom
Advances in high-resolution and spin-resolved scanning tunnelling microscopy, as well as atomic-scale manipulation, have enabled the bottom-up, atom-by-atom creation and characterization of quantumExpand
