Billions of years in the future, The Time Traveler stands before a black ocean, under a bloated sun. The shore is scaled with lichen and flecked with snow. The crab things and giant insects that menaced him on his visit millions of years in its past are gone. Apart from the lapping of dark waves, everything is utterly still.

He thinks he sees something shifting in the waves nearby but dismisses it as an illusion; assuming it to be a rock. Still a churning weakness and fear deters him from leaving the saddle of the time machine. Perhaps this anxiety is just prompted by the ultimate desolation of this world.

Studying the unknown constellations, he feels a chill wind. The old sun is being eclipsed by the moon, or some other massive body – for it is possible that the Earth has shifted into a new orbit around its star.

Has the technological singularity in 2019 changed since the late 1990s?

As a theoretical concept it has become more recognized. As a potential threat, it is significantly written about and talked about. Because the field of narrow AI is growing and machine learning has found a place in academics and entrepreneurs are investing in the growth of AI, tech leaders have come to the table and voiced their concerns, especially Bill Gates, Elon Musk, and the late Stephen Hawking. The concept of existential risk has taken a central position within the discussions about AI and machine ethicists are prepping their arguments toward a consensus that near-future robots will force us to rethink the exponential advances in the fields of robotics and computer science. Here it is crucial for those leaders in philosophy and ethics to address the concept of what an ethical machine means and the true goal of machine ethics.

Quantum entanglement is one of the most fundamental and intriguing phenomena in nature. Recent research on entanglement has proven to be a valuable resource for quantum communication and information processing. Now, scientists from Japan have discovered a stable quantum entangled state of two protons on a silicon surface, opening doors to an organic union of classical and quantum computing platforms and potentially strengthening the future of quantum technology.

One of the most interesting phenomena in quantum mechanics is “quantum entanglement.” This phenomenon describes how certain particles are inextricably linked, such that their states can only be described with reference to each other. This particle interaction also forms the basis of quantum computing. And this is why, in recent years, physicists have looked for techniques to generate entanglement. However, these techniques confront a number of engineering hurdles, including limitations in creating large number of “qubits” (quantum bits, the basic unit of quantum information), the need to maintain extremely low temperatures (1 K), and the use of ultrapure materials. Surfaces or interfaces are crucial in the formation of quantum entanglement. Unfortunately, electrons confined to surfaces are prone to “decoherence,” a condition in which there is no defined phase relationship between the two distinct states.

Entanglement is an ubiquitous concept in modern physics research: it occurs in subjects ranging from quantum gravity to quantum computing. In a publication that appeared in Physical Review Letters last week, UvA-IoP physicist Michael Walter and his collaborator Sepehr Nezami shed new light on the properties of quantum entanglement—in particular, for cases in which many particles are involved.

In the quantum world, physical phenomena occur that we never observe in our large scale everyday world. One of these phenomena is quantum entanglement, where two or more quantum systems share certain properties in a way that affects measurements on the systems. The famous example is that of two electrons that can be entangled in such a way that—even when taken very far apart—they can be observed to spin in the same direction, say clockwise or counterclockwise, despite the fact that the spinning direction of neither of the individual electrons can be predicted beforehand.

This is the third time a Long March 5B booster has made an uncontrolled reentry.

Looking at just one week in Trends exposes the grave problems that remain with this feature, despite the platform’s many attempts to fix it.

Microsoft’s big defense contract that looks to supply the US Army with modified HoloLens AR headsets isn’t going so well. As first reported by Bloomberg, the Senate panel that oversees defense spending announced significant cuts to the Army’s fiscal 2023 procurement request for the device.

Microsoft announced last year it had won a US Army defense contact worth up to $22 billion to develop an Integrated Visual Augmentation System (IVAS), a tactical AR headset for soldiers based on HoloLens 2 technology.

Now the Appropriations Defense Subcommittee announced it’s cut $350 million from the Army’s procurement plans for IVAS, leaving around $50 million for the device. The subcommittee cites concerns based around the program’s overall effectiveness.

Smartphone ownership (85%) and home broadband subscriptions (77%) have increased among American adults since 2019 – from 81% and 73% respectively. Though modest, both increases are statistically significant and come at a time when a majority of Americans say the internet has been important to them personally. And 91% of adults report having at least one of these technologies.

A Pew Research Center survey of U.S. adults conducted from Jan. 25 to Feb. 8, 2021, also finds that some Americans have difficulties when trying to go online. Some 30% of adults say they often or sometimes experience problems connecting to the internet at home, including 9% who say such problems happen often. Still, a majority of Americans say these connection troubles occur rarely (41%) or never (21%).

While there has been slight growth in the share who say they subscribe to high-speed internet, about a quarter of the population still does not have a broadband internet connection at home. And broadband non-adopters continue to cite financial constraints as one of the most important reasons why they forgo these services. Among non-broadband users, 45% say a reason why they do not have broadband at home is that the monthly cost of a home broadband subscription is too expensive, while about four-in-ten (37%) say the same about the cost of a computer. Beyond cost barriers, a little fewer than half of non-users cite having other options for internet access or the fact that their smartphone does everything online they need as a reason why they do not have a high-speed internet connection at home.
