Imaging current flow and injection in scalable graphene devices through NV-magnetometry

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Kaj Dockx, Michele Buscema, Saravana Kumar, Tijmen van Ree, Abbas Mohtashami | Summary: The global electronic properties of solid-state devices are strongly affected by the microscopic spatial paths of charge carriers. Visualising these paths in novel devices produced by scalable processes would provide a quality […]

Imaging orbital Rashba induced charge transport anisotropy

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Eylon Persky, Xi Wang, Giacomo Sala, Thierry C. van Thiel, Edouard Lesne | Summary: Identifying orbital textures and their effects on the electronic properties of quantum materials is a critical element in developing orbitronic devices. However, orbital effects are often entangled with the spin degree of […]

Braiding Majoranas in a linear quantum dot-superconductor array: Mitigating the errors from Coulomb repulsion and residual tunneling

Kavli Affiliate: Michael Wimmer | First 5 Authors: Sebastian Miles, Francesco Zatelli, A. Mert Bozkurt, Michael Wimmer, Chun-Xiao Liu | Summary: Exchanging the positions of two non-Abelian anyons transforms between many-body wavefunctions within a degenerate ground-state manifold. This behavior is fundamentally distinct from fermions, bosons and Abelian anyons. Recently, quantum dot-superconductor arrays have emerged as […]

A flux-controlled two-site Kitaev chain

Kavli Affiliate: Srijit Goswami | First 5 Authors: Ivan Kulesh, Sebastiaan L. D. ten Haaf, Qingzhen Wang, Vincent P. M. Sietses, Yining Zhang | Summary: In semiconducting-superconducting hybrid devices, Andreev bound states (ABSs) can mediate the coupling between quantum dots (QDs), allowing for the realisation of artificial Kitaev chains. In order to engineer Majorana bound […]

Time-resolved spectral diffusion of a multimode mechanical memory

Kavli Affiliate: Simon Groblacher | First 5 Authors: Niccolò Fiaschi, Lorenzo Scarpelli, Alexander Rolf Korsch, Amirparsa Zivari, Simon Gröblacher | Summary: High-frequency phonons hold great promise as carriers of quantum information on-chip and as quantum memories. Due to their coherent interaction with several systems, their compact mode volume and slow group velocity, multiple experiments have […]

Heitler effect and resonance fluorescence in quantum magnonics

Kavli Affiliate: Ya M. Blanter | First 5 Authors: Enes Ilbuğa, V. V. Dobrovitski, Ya. M. Blanter, , | Summary: We consider a coupled system of a qubit and a magnon mode in which the qubit is weakly driven. We demonstrate that the spectral steady-state responses of both the qubit and the magnon show, in […]

The quantum Kibble-Zurek mechanism: the role of boundary conditions, endpoints and kink types

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Jose Soto Garcia, Natalia Chepiga, , , | Summary: Quantum phase transitions are characterised by the universal scaling laws in the critical region surrounding the transitions. This universality is also manifested in the critical real-time dynamics through the quantum Kibble-Zurek mechanism. In recent experiments on a Rydberg […]
