Chiral adiabatic transmission protected by Fermi surface topology

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Isidora Araya Day, Kostas Vilkelis, Antonio L. R. Manesco, A. Mert Bozkurt, Valla Fatemi | Summary: We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet. The chirality and the number of quantized […]

Gate modulation of the hole singlet-triplet qubit frequency in germanium

Kavli Affiliate: Menno Veldhorst | First 5 Authors: John Rooney, Zhentao Luo, Lucas E. A. Stehouwer, Giordano Scappucci, Menno Veldhorst | Summary: Spin qubits in germanium gate-defined quantum dots have made considerable progress within the last few years, partially due to their strong spin-orbit coupling and site-dependent $g$-tensors. While this characteristic of the $g$-factors removes […]

Entanglement buffering with two quantum memories

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Bethany Davies, Álvaro G. Iñesta, Stephanie Wehner, , | Summary: Quantum networks crucially rely on the availability of high-quality entangled pairs of qubits, known as entangled links, distributed across distant nodes. Maintaining the quality of these links is a challenging task due to the presence of time-dependent […]
