TL;DR: It is demonstrated that a large topological Hall effect develops well below the Néel temperature as soon as the spin arrangement changes from collinear to non-collinear with decreasing temperature, and is not observed when the material is turned ferromagnetic by carbon doping without changing its crystal structure.

TL;DR: In this article, a fluxonium qubit design based on a granular aluminium superinductor strip was presented, which can form an effective junction array with high kinetic inductance and be in situ integrated with standard aluminium circuit processing.

TL;DR: In this article, a fluxonium qubit design using a granular aluminum superinductor strip was presented, which self-assembles into an effective junction array with a remarkably high kinetic inductance, and its fabrication can be in-situ integrated with standard aluminum processing.

TL;DR: The authors show that resonators made from granular aluminum, which naturally realizes a network of Josephson junctions, have practically useful impedances and nonlinearities.

TL;DR: In this article, a non-degenerate parametric amplifier with state discrimination was used to detect quantum jumps of a transmon qubit with a fidelity of 90% of state discrimination.
