Efficient driving of a spin-qubit using single-atom magnets
Jose Reina-Gálvez, Hoang-Anh Le, Hong Thi Bui +3
The realization of electron-spin resonance at the single-atom level using scanning tunneling microscopy has opened new avenues for coherent quantum sensing and quantum state manipu…
Contrasting exchange-field and spin-transfer torque driving mechanisms in all-electric electron spin resonance
Jose Reina-Galvez, Matyas Nachtigall, Nicolas Lorente +2
Understanding the coherent properties of electron spins driven by electric fields is crucial for their potential application in quantum-coherent nanoscience. In this work, we addre…
Spin-State Engineering of Single Titanium Adsorbates on Ultrathin Magnesium Oxide
Soo-hyon Phark, Hong Thi Bui, We-hyo Seo +7
Single atomic adsorbates on ultrathin insulating films provide a promising route toward bottom-up quantum architectures based on atomically identical yet individually addressable s…
Microscopic Scattering Approach to In-Gap States: Cr Adatoms on Superconducting β-Bi2Pd
Joseph Sink, Hari Paudyal, Divya Jyoti +4
We develop a microscopic scattering formalism to describe Yu-Shiba-Rusinov (YSR) states due to a single Cr adatom on the Bi-terminated surface of , by combining ab initi…
Electron spin resonance with scanning tunneling microscopy: a tool for an on-surface quantum platform of identical qubits
Deung-Jang Choi, Soo-hyon Phark, Andreas J. Heinrich +1
Integration of electron spin resonance (ESR) in a scanning tunneling microscope (STM) has enabled an all-electrical control of atomic and molecular spins on solid surfaces with ato…
Unraveling spin entanglement using quantum gates with scanning tunneling microscopy-driven electron spin resonance
Eric D. Switzer, Jose Reina-Gálvez, Géza Giedke +4
Quantum entanglement is a fundamental resource for quantum information processing, and its controlled generation and detection remain key challenges in scalable quantum architectur…
