Overview of results
In this paper, we will mainly focus on stabilizer trees whose vertices correspond to the same encoder of a stabilizer code, and whose edges are subject to the same single-qubit Pauli noise (see Sec. Setup: Noisy Quantum Trees)….

Tunable high Néel temperature and large anomalous Hall response in antiferromagnetic Weyl semimetal Mn3Sn1−xGax thin films
Figure 1a shows the crystal structure of the hexagonal Mn3X(X = Ge, Sn, Ga) compounds where kagome planes of Mn atoms in ABAB stacking along the c-axis host an antichiral magnetic structure with a dominant cluster octupolar moment. The…

Ice Dissolves Iron Minerals More Effectively than Liquid Water: Study
Ice at minus 10 degrees Celsius releases more iron from common minerals than liquid water at 4 degrees Celsius, according to a team of researchers from Umeå University, the Institut des Sciences Chimiques de Rennes and CNRS. This discovery…

The Universe’s first magnetic fields were shockingly weak, but changed everything
The magnetic fields that formed in the very early stages of the Universe, may have been billions of times weaker than a small fridge magnet, with strengths comparable to magnetism generated by neurons in the human brain. Yet, despite such…

Physics – Superradiance Without Entanglement
• Physics 18, s118
Scientists have shown that entanglement plays no role in a form of collective light emission called Dicke superradiance, settling a long-standing debate.

Coupled non-Hermitian skin effect with exceptional points
Effective coupling induced by AGF
We start with a one-dimensional photonic waveguide lattice as illustrated in Fig. 1a. The lattice is composed of sublattices A and B with on-site losses denoted by \({\gamma }_{A}\) and \({\gamma }_{B}\),…
