Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Wolfgang Tittel, Mikael Afzelius, Adam Kinos, Lars Rippe, Andreas Walther | Summary: We review concepts and recent work related to creating light-matter interfaces for future quantum networks based on rare-earth ion-doped crystals. More precisely, we explore their unique suitability for creating photon sources, optical quantum memories for […]

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 […]

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 […]

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Antonija Grubišić-Čabo, Marcos H. D. Guimarães, Dmytro Afanasiev, Jose H. Garcia Aguilar, Irene Aguilera | Summary: Fundamental research on two-dimensional (2D) magnetic systems based on van der Waals materials has been gaining traction rapidly since their recent discovery. With the increase of recent knowledge, it […]

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Manu Canals, Natalia Chepiga, Luca Tagliacozzo, , | Summary: The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ansatz for gauge-invariant states as originally discussed in [Phys. Rev. B […]

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Haoran Lu, Isidora Araya Day, Anton R. Akhmerov, Bernard van Heck, Valla Fatemi | Summary: We propose an architecture for bit flip error correction of Andreev spins that is protected by Kramers’ degeneracy. Specifically, we show that a coupling network of linear inductors results in a […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Valentin John, Cécile X. Yu, Barnaby van Straaten, Esteban A. Rodríguez-Mena, Mauricio Rodríguez | Summary: Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for textit{in situ} electric fast and high-fidelity qubit gates. However, the interaction also […]
