Submission + - Researchers Build Quantum Antenna to Precisely Measure Terahertz Signals (scitechdaily.com)

fahrbot-bot writes: SciTechDaily is reporting that a research team has created a quantum antenna capable of precisely measuring terahertz frequency combs for the first time.

A research team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the Centre of New Technologies, University of Warsaw has introduced a new approach for detecting extremely weak terahertz signals by using a “quantum antenna.” Their method relies on a specialized system that employs Rydberg atoms for radio wave detection, allowing them not only to capture these signals but also to accurately calibrate a frequency comb in the terahertz range.

This part of the electromagnetic spectrum was considered largely unexplored until recently, and the breakthrough, reported in Optica, offers a pathway toward highly sensitive spectroscopy and a new class of quantum sensors that can function at room temperature.

Terahertz (THz) radiation occupies a unique position within the electromagnetic spectrum, sitting between microwaves (such as those used in Wi-Fi) and infrared light at the intersection of electronics and optics. It promises a wide range of applications, including scanning packages without harmful X-rays, enabling ultra-fast 6G communication, and advancing spectroscopy and organic compound imaging.

..."Kill 10 Ukrainian soldiers, and you get your game back."

Ukraine is doing something like that... Ukrainian computer game-style drone attack system goes ‘viral'

System rewards soldiers who achieve strikes with points that can be used to buy more weapons in an online store.

The number of Russian casualties in September is double the number from last October, in part because the Kyiv government doubled the rewards for killing Russian infantry from six to 12 points, reflecting changing battlefield priorities. ... killing an enemy drone operator now earns 25 points and using a drone to capture a Russian soldier attracts 120 points

A BBC article, Kill Russian soldiers, win points: Is Ukraine's new drone scheme gamifying war? notes:

... destroying an enemy multiple rocket launch system earns up to 50 points; 40 points are awarded for a destroyed tank and 20 for a damaged one.

SIM-locking should be banned, period. Works well in many other countries. There is no valid reason to SIM-lock a phone, even for 60 days or 60 days of active paid service. It's a net loss to society as a whole. Even though I understand it can benefit Verizon in one case, it also prevented someone else to switch to Verizon from a competitor.

I think people in other countries generally buy their phones outright, rather than via provider payment plans, often at a discount, like in the U.S. and I think SIM locking is to prevent people from switching providers before those phones are paid off - and so the providers don't have to sue to recoup that money. That's probably reasonable, but doing it to just make it harder for people to switch is not. Of course, most phones smartphones probably aren't paid off after 60 days, unless providers have another avenue to recoup the money for the device, so I don't know how a policy works in that case.

From Cell Phone Unlocking:

Locked phones are often sold at a reduced price or as part of an installment plan. They remain locked until all the installments are paid, or for a certain period of time to ensure the phone is used on the network of the provider that sold the phone at a discount.

Even when paying full price for a cell phone, it may be locked for a short period of time, such as 60 days, to help prevent theft and certain types of fraud. Providers may have different unlocking policies for their prepaid and postpaid monthly service plans.

As for me, I bought my three successive cell phones over the last 26 years. unlocked and in full.

Except the workforce doesn't become optional in any case. It becomes absolutely redundant, and it will be eliminated.
In a globalized capitalist society without any guardrails, it can be assumed that if there is a way to optimize something to provide greater shareholder value / CEO pay and bonuses, it will be done. Just as if something was cheaper to produce in Asia, virtually all of that work will be done in Asia; if AI does something, anything less expensively than a laborer, that work will be moved to AI. That is not to say that some workers may be kept around as tokens, or objects of abuse--bullying robots just doesn't have the same feel.; they will be like the caucasians employed in Hong Kong. Look at us! We are doing well enough to employ a useless white guy!

In this world, It's a constant race to the bottom, consequences be damned. If AI cuts the legs off the working class, and ultimately the whole economy topples as a result, they will not care, so long as the financial quarter before the collapse was the best, most profitable quarter ever.

Comment Re:94% of Trump's cases lose in lower courts (Score 1) 133

And 94% of them are overturned in favor of Trump when they get to the Supreme court, usually on the shadow docket with absolutely no reason given. The system of checks and balances designed to protect you have failed. All of them.

The lower courts getting overturned by a higher court is part of that system of checks and balances. Many people think it's the lower courts that are failing.

Many of the lower court decisions seem pretty solid, reasonable and thought-out, but SCOTUS, especially Justices Alito and Thomas, is seemingly just making stuff up, or misinterpreting things from Medieval England, to support their agendas.

Alito's Roe attack betrays a medieval ignorance of ancient history

Many of their rulings that specifically favored Trump seem like stretches, like the near-total immunity for the President and limiting the application of the insurrection clause for presidential candidates. It'll be interesting to see how they re-interpret things when a Democrat is in the office - I'm guessing 3-6 will then see things differently.

That's gotta really torque Trump off. :-)

"It's more symbolic than substantive," he said. "All the court is saying is ... you need to go back to work and consider these applications. What does that really mean?" he said. Officials could still deny permits or bog applications down in lengthy reviews, he noted.

Sure, but companies only have to wait 3 more years ...

if you're an internet platform you get treated one way; you do the exact same thing and you're a publisher, you get treated a completely different way.

This is a false comparison. ISPs generally don't (get to) pick their customers and don't select, edit, and curate those customers content, publishers do both. Publishers have a direct hand in who and what gets published and when, ISP generally don't. Granted, ISPs could be (more) selective in who they signup, like publishers, but that would be hugely labor-intensive and not cost effective given the scale of ISP customers vs. publishers. Even then ISP wouldn't (generally) get involved in their customer's content - as that would get them into trouble under Section 230 (if I understand things correctly). All subject to Terms and Conditions, your mileage may vary, etc ...

Maybe if the whale killers get reinstated we'll at least get case law to prohibit permitting denials for Integral Fast Reactors and that can at least clean up the Boomers' nuclear waste to protect the ecosystem long term.
