The techniques of microwave quantum optics are applied to collective spin excitations in a macroscopic sphere of ferromagnetic insulator. We demonstrate.

In the single-magnon limit, strong coupling between a magnetostatic mode in the sphere and a microwave cavity mode. Moreover, we introduce a superconducting qubit in the cavity and couple the qubit with the magnon excitation via the virtual photon excitation. We observe the magnon-vacuum-induced Rabi splitting.

The hybrid quantum system enables generation and characterization of non-classical quantum states of magnons.

DARPA’s Air Combat Evolution program aims to find out — and so shape America’s future arsenal.

A U.S. military research program is advancing the study of humans and machines working together by testing how well pilots and artificially intelligent entities trust each other in one of the most challenging of tasks: aerial combat, or dogfighting.

The idea behind DARPAs Air Combat Evolution, or ACE, program, is that human fighter pilots will soon be flying alongside increasingly capable drones — dubbed “Loyal Wingmen” — that will help evade other fighters and air defenses. Military leaders often describe the F-35 Joint Strike Fighter as a kind of flying command center, with the human operator working less like a traditional pilot and more like a team captain. The craft is loaded with AI features that pilots say make it easier to fly than traditional fighters. That enables the pilot to digest and put to use the immense amount of data the F-35 pulls in.

Elon Musk’s appearance at Tesla owner-enthusiast Ryan McCaffrey’s Ride the Lightning podcast revealed a number of new details about the electric car maker’s upcoming halo vehicle, the next-generation Roadster. While addressing the all-electric supercar, Musk discussed the vehicle’s estimated yearly production numbers, its purpose, and some details about its “SpaceX package.”

Ever the candid interviewee, Musk admitted that the next-generation Roadster is really more like a dessert to the Model S, 3, X, and Y’s main course, in the way that its existence will probably not provide much of an impact to Tesla’s overall mission of accelerating the world’s transition to sustainable energy. Nevertheless, the Roadster still has a lot of merits, in the way that it could establish the superiority of pure electric propulsion compared to the internal combustion engine, bar none.

Musk noted that the Roadster is intended to outperform the best “Ferraris, Lamborghinis, and McLarens” on every dimension, on every level, including the track, thereby erasing the halo effect of gas cars. “We’re going to do things with the new Roadster that are kind of unfair to other cars. (It’s) crushingly good relative to the next best gasoline sports car,” Musk said.

As impressive as such technology has been among gamers, many artificial-intelligence experts question whether it will ultimately translate to solving real-world problems. DeepMind’s agents are not really collaborating, said Mark Riedl, a professor at Georgia Tech College of Computing who specializes in artificial intelligence. They are merely responding to what is happening in the game, rather than trading messages with one another, as human players do. (Even mere ants can collaborate by trading chemical signals.)

Chess and Go were child’s play. Now A.I. is winning at capture the flag. Will such skills translate to the real world?

The way information travels inside the cells of our bodies is not unlike the wiring inside a computer chip, according to a new study that has unveiled the intricate workings of a network of calcium ions as intracellular messengers.

According to researchers from the University of Edinburgh in the UK, this “cell-wide web” uses a microscopic network of guides to transmit information across nanoscale distances and carry activities and instructions for the cells to perform — such as relaxing or contracting muscles, for example.

Calcium ions (Ca2+) are a fundamental part of the messaging system of our cells, and their signals are crucial for a wide variety of jobs, including cell growth, death, and movement. Now researchers have taken an unprecedented close look at just how calcium ions shuttle messages within the cell.
