Quoted from one of the authors in a separate interview: "We know that the spin states of atomic nuclei associated with semiconductor defects have excellent quantum properties at room temperature," said Awschalom, Liew Family Professor in Molecular Engineering and a senior scientist at Argonne National Laboratory. "They are coherent, long-lived and controllable with photonics and electronics. Given these quantum 'pieces,' creating entangled quantum states seemed like an attainable goal." Bringing the quantum world to the macroscopic scale could see some interesting applications in sensors, or generally entanglement-enhanced applications.

They were previously working on the same concept in N-V centers in diamond (as a semiconductor). Here the advantage is that SiC could in principle be integrated with Si or Ge. Anyway its all about controlling coherence. In the next 10 years some breakthroughs are expected in the field of semiconductor spintronics, but quantum computing in this way lies still in the horizon

A revolutionary new type of laser (fiber laser) is promising major advances in remote sensing of greenhouse gases.The new laser can operate (bed tuned) over a large range within the infrared light spectrum.

Reads too good to be true .... where is Isabelle when we need her ? :-)

Paper: https://arxiv.org/abs/1806.02404

Dataset automatically constructed from public images uploaded by users on FB/Instagram with hashtags used as labels! They refer to this as 'weakly supervised learning'. Then neural net fine-tuned for ImageNet and achieved record 85.4% accuracy.

"Publishing industry exerts too much influence over what scientists choose to study, which is ultimately bad for science itself"

On a related topic - a nice read written in 1939 from Abraham Flexner the founder of Institute for Advanced Study in Princeton, home of some great minds on the "Usefulness of Useless Knowledge". Enjoy https://library.ias.edu/files/UsefulnessHarpers.pdf

This article is fantastic - starts already well with : "r IT not a curious fact that in a world steeped in irrational hatreds which threaten civilization itself, men and women-old and young-detach them-selves wholly or partly from the angry current of daily life to devote themselves to the cultivation ofbeauty, to the exten-sion ofknowledge, to the cure ofdisease, to the amelioration of suffering, just as though fanatics were not simultaneously engaged in spreading pain, ugliness, and suffering?" Could almost be written now

A new class of exotic materials could find its way into next-generation technologies that efficiently convert waste heat into electrical current according to new research. Both the exotic materials and the means by which they generate electricity rely on a hybrid of advanced concepts-including string theory combined with black holes combined with cutting-edge condensed matter physics.

Sounds spooky

"In contrast to conventional multipixel cameras, single-pixel cameras capture images using a single detector that measures the correlations between the scene and a set of patterns. However, these systems typically exhibit low frame rates, because to fully sample a scene in this way requires at least the same number of correlation measurements as the number of pixels in the reconstructed image."

Is that the same method Andrej and Jai use in their super-telescope Ariadna?

appears like solid data confirming the link between the two; using also EO data from space
