"Men DN är väl förlorade nu och sedan följer resten av media efter. SvD skriver ju redan ren Putinpropaganda, och det blir väl det sista som är kvar. Tyvärr är kriget ett maraton och Ryssland, Moskva, Kreml och Putin har tiden att nöta ner intresset och sprida sin propaganda."

UPPDATERAS: Ny stor rysk terrorbombning med robotar - DN tar bort Ukraina från förstasidan - mobiliseringslagen genomröstad
Ryssland genomförde under natten och morgonen en ny stor terrorbombning med kryssningsrobotar och ballistiska robotar mot den ukrainska energisektorn. Ukrainas parlament har röstat igenom den nya mobiliseringslagen. Sveriges största dagstidning DN har tagit bort sin Ukrainalänk från sin förstasida.

@… Question to you and maybe other #podcastTech providers: your Overcast/1.0 Podcast Sync host does not seem to use If-Modified-Since or honour skipHours: does anyone? Wouldn't everyone like to crunch their bandwidth bill and footprint?

QRAM architectures using superconducting cavities
Quantum random access memory (QRAM) is a common architecture resource for algorithms with many proposed applications, including quantum chemistry, windowed quantum arithmetic, unstructured search, machine learning, and quantum cryptography. Here we propose two bucket-brigade QRAM architectures based on high-coherence superconducting resonators, which differ in their realizations of the conditional-routing operations. In the first, we directly construct controlled-$\mathsf{SWAP}$ ($\textsf{CSWAP…

Suppression of flux jumps in high-$J_c$ Nb$_3$Sn conductors by ferromagnetic layer
Flux jumps observed in high-$J_c$ Nb$_3$Sn conductors are urgent problems to construct high field superconducting magnets. The low-field instabilities usually reduce the current-carrying capability and thus cause the premature quench of Nb$_3$Sn coils at low magnetic field. In this paper, we explore suppressing the flux jumps by ferromagnetic (FM) layer. Firstly, we experimentally and theoretically investigate the flux jumps of Nb$_3$Sn/FM hybrid wires exposed to a magnetic field loop with cons…

Non-local transport measurements in hybrid quantum Hall - superconducting devices
There has been a growing interest in hybrid quantum Hall (QH) superconductor devices, driven by the prospect to realize exotic ground states and excitations with non-abelian exchange statistics. While the existing experiments clearly demonstrate Andreev coupling between the edge states and the superconductors, the question remains whether the quantum coherence could propagate between several superconducting contacts via chiral channels. To answer this question, we have first extended the Landau…

Recovering quantum coherence of a cavity qubit through environment monitoring and active feedback
Decoherence in qubits, caused by their interaction with a noisy environment, poses a significant challenge to developing reliable quantum processors. Monitoring the qubit's environment enables not only to identify decoherence events but also to reverse these errors, thereby restoring the qubit coherence. This approach is particularly beneficial for superconducting cavity qubits, whose unavoidable interaction with auxiliary transmons impacts their coherence. In this work, we uncover the intricat…
