Theory of Electron Spin Resonance Scanning Tunneling Microscopy: The First Decade
Saba Taherpour, Denis Janković, Jose Reina-Galvez +2
Electron spin resonance in scanning tunneling microscopy enabled the study of electronic transitions of magnetic impurities on surfaces at the atomic scale. This ESR-STM technique…
Probing the Weak-Driving Quantum Speed Limit via Drift-Aware Shooting Methods
Denis Janković, Saba Taherpour, Paul-Louis Etienney +2
A central goal of quantum optimal control is to achieve high-fidelity and low-energy control pulses. When quantum optimal control methods optimize every point of a pulse discretize…
The hyperfine interaction as a probe of the microscopic structure of the atomic nucleus
Denis Janković, Jean-Gabriel Hartmann, Johann Bartel +3
The study of highly charged electronic and muonic hydrogen-like ions, provides an intriguing way to probe the internal structure of their atomic nuclei. In this work, we use nuclea…
Overcoming limitations on gate fidelity in noisy static exchange-coupled surface qubits
Hoang-Anh Le, Saba Taherpour, Denis Janković +1
Recent experiments demonstrated that the spin state of individual atoms on surfaces can be quantum-coherently controlled through all-electric electron spin resonance. By constructi…
