Coherent spin–photon coupling using a resonant exchange qubit

Pasquale Scarlino

Electron spins hold great promise for quantum computation because of their long coherence times. Long-distance coherent coupling of spins is a crucial step towards quantum information processing with spin qubits. One approach to realizing interactions betw ...

Dimerization and exotic criticality in spin-S chains

Natalia Chepiga

In this thesis we have studied the emergence of spontaneously dimerized phases in frustrated spin-S chains, with emphasis on the nature of the critical lines between the dimerized and non-dimerized phases. The main numerical method used in this thesis is t ...

Electron Spin Dynamics of Two-Dimensional Layered Materials

László Forró, Bálint Náfrádi

The growing library of two-dimensional layered materials is providing researchers with a wealth of opportunity to explore and tune physical phenomena at the nanoscale. Here, we review the experimental and theoretical state-of-art concerning the electron sp ...

Atomic-scale sensing of the magnetic dipolar field from single atoms

Donat Fabian Natterer

Spin resonance provides the high-energy resolution needed to determine biological and material structures by sensing weak magnetic interactions(1). In recent years, there have been notable achievements in detecting(2) and coherently controlling(3-7) indivi ...

The valley degree of freedom is intrinsic to spin qubits in Si/SiGe quantum dots. It has been viewed alternately as a hazard, especially when the lowest valley-orbit splitting is small compared to the thermal energy, or as an asset, most prominently in pro ...

Room temperature manipulation of long lifetime spins in metallic-like carbon nanospheres

László Forró, Bálint Náfrádi

The time-window for processing electron spin information (spintronics) in solid-state quantum electronic devices is determined by the spin-lattice and spin-spin relaxation times of electrons. Minimizing the effects of spin-orbit coupling and the local magn ...

Probing Entangled States of the Nuclear-Electronic Quantum Magnet LiHoF₄

Ivan Kovacevic

Two objects are entangled when their quantum mechanical wavefunctions cannot be written in a separable product form. Entangling dissimilar quantum objects, or hybridization, has been suggested as a promising route to efficient quantum information processor ...

Controlling the Spin of Co Atoms on Pt(111) by Hydrogen Adsorption

Harald Brune, Christian Wäckerlin, Pietro Gambardella, Fabio Donati, Markus Etzkorn, Anne Lehnert, Quentin Dubout, Laurent Claude

We investigate the effect of H adsorption on the magnetic properties of individual Co atoms on Pt(111) with scanning tunneling microscopy. For pristine Co atoms, we detect no inelastic features in the tunnel spectra. Conversely, CoH and CoH2 show a number ...

One-loop effects from spin-1 resonances in Composite Higgs models

Roberto Contino

We compute the 1-loop correction to the electroweak observables from spin-1 resonances in SO(5)/SO(4) composite Higgs models. The strong dynamics is modeled with an effective description comprising the Nambu-Goldstone bosons and the lowest-lying spin-1 res ...

Control and coherence of Loss-DiVincenzo qubits in Si/SiGe quantum dots

Pasquale Scarlino

Electron spins in Si/SiGe quantum dots are one of the most promising candidates for a quantum bit for their potential to scale up and their long dephasing time. We report for the first time the experimental realization of single electron spin rotations in ...
