The Turing Trap: The Promise & Peril of Human-Like Artificial Intelligence

Posted by in category: robotics/AI

This highlights the promise and the peril of achieving HLAI: building machines designed to pass the Turing Test and other, more sophisticated metrics of human-like intelligence.8 On the one hand, it is a path to unprecedented wealth, increased leisure, robust intelligence, and even a better understanding of ourselves. On the other hand, if HLAI leads machines to automate rather than augment human labor, it creates the risk of concentrating wealth and power. And with that concentration comes the peril of being trapped in an equilibrium where those without power have no way to improve their outcomes, a situation I call the Turing Trap.

The grand challenge of the coming era will be to reap the unprecedented benefits of AI, including its human-like manifestations, while avoiding the Turing Trap. Succeeding in this task requires an understanding of how technological progress affects productivity and inequality, why the Turing Trap is so tempting to different groups, and a vision of how we can do better.

Quantum watch is a ‘completely new way of measuring time’

Posted by in categories: particle physics, quantum physics

O.o!!! It doesn’t need seconds counted it just knows the time on the quantum level o.o!!!!!


A quantum stopwatch made of lasers and helium atoms can measure the time that has passed with complete accuracy, without counting seconds like other clocks.

Children’s hospitals grapple with a nationwide surge in RSV infections

Posted by in categories: biotech/medical, health

“This year, parents are sending their children to daycare and school for the first time following two years of the pandemic. … Children who haven’t been previously exposed to respiratory viruses are getting sick,” Romano said.

Health officials in King County, Wash., are also alarmed as they brace for more cases once winter hits. Dr. Russell Migita with Seattle Children’s Hospital told King 5 News they are seeing about 20 to 30 positive cases every day, adding that those are “unprecedented” figures.

Toward Flawless Atom Optics

Posted by in categories: computing, engineering, particle physics, quantum physics, space

The engineering of so-called Floquet states leads to almost-perfect atom-optics elements for matter-wave interferometers—which could boost these devices’ ability to probe new physics.

Since Michelson and Morley’s famous experiment to detect the “luminiferous aether,” optical interferometry has offered valuable tools for studying fundamental physics. Nowadays, cutting-edge applications of the technique include its use as a high-precision ruler for detecting gravitational waves (see Focus: The Moon as a Gravitational-Wave Detector) and as a platform for quantum computing (see Viewpoint: Quantum Leap for Quantum Primacy). But as methods for cooling and controlling atoms have advanced, a new kind of interferometer has become available, in which light waves are replaced by matter waves [1]. Such devices can measure inertial forces with a sensitivity even greater than that of optical interferometers [2] and could reveal new physics beyond the standard model.

Frequency Comb Measures Quantum Interference

Posted by in categories: particle physics, quantum physics

A multiwavelength laser source known as a frequency comb provides a new technique for atom interferometry, potentially leading to new tests of fundamental physics.

In atom interferometry, researchers use the interference of quantum waves of matter, often for high-precision experiments testing fundamental physics principles. A research team has now demonstrated a new way to produce matter-wave interference by using a frequency-comb laser—a comb-like set of spectral lines at regularly spaced frequencies [1]. The comb allowed the team to generate interference in a cloud of cold atoms. The method might ultimately be used to investigate differences between matter and antimatter.

According to the weak equivalence principle, gravity must cause both matter and antimatter to fall at the same rate (see the graphical explanation, The Equivalence Principle under a MICROSCOPE). Deviations from this principle could point to explanations for the hitherto mysterious imbalance in the amounts of matter and antimatter in the Universe. Atom interferometry could provide a test of weak equivalence through precise measurements of the free fall of antihydrogen. So far, light-based control of atom interferometry has used continuous-wave (cw) lasers [2], which can’t easily be extended to the short wavelengths in the extreme ultraviolet (XUV) that are needed for such studies of antihydrogen.
