Entangled quantum circuits further disprove Einstein’s concept of local causality

Posted by in categories: computing, quantum physics

A group of researchers led by Andreas Wallraff, Professor of Solid State Physics at ETH Zurich, has performed a loophole-free Bell test to disprove the concept of “local causality” formulated by Albert Einstein in response to quantum mechanics.

By showing that quantum mechanical objects that are far apart can be much more strongly correlated with each other than is possible in conventional systems, the researchers have provided further confirmation for . What’s special about this experiment is that the researchers were able for the first time to perform it using , which are considered to be promising candidates for building powerful quantum computers.

A Bell test is based on an experimental setup that was initially devised as a by British physicist John Bell in the 1960s. Bell wanted to settle a question that the greats of physics had already argued about in the 1930s: Are the predictions of quantum mechanics, which run completely counter to everyday intuition, correct, or do the conventional concepts of causality also apply in the atomic microcosm, as Albert Einstein believed?

Light amplification

Posted by in categories: chemistry, computing, quantum physics

In a result decades in the making, Los Alamos scientists have achieved light amplification with electrically driven devices based on solution-cast semiconductor nanocrystals—tiny specs of semiconductor matter made via chemical synthesis and often called colloidal quantum dots.

This demonstration, reported in the journal Nature, opens the door to a completely new class of electrically pumped lasing devices—highly flexible, solution-processable laser diodes that can be prepared on any crystalline or non-crystalline substrate without the need for sophisticated vacuum-based growth techniques or a highly controlled clean-room environment.

“The capabilities to attain light amplification with electrically driven colloidal have emerged from decades of our previous research into syntheses of nanocrystals, their photophysical properties and optical and electrical design of quantum dot devices,” said Victor Klimov, Laboratory Fellow and leader of the quantum dot research initiative.

Microsoft just made a huge, far-from-certain bet on nuclear fusion

Posted by in category: nuclear energy

Scientists have been dreaming about nuclear fusion for decades. Microsoft thinks the technology is nearly ready to plug into the grid.

Microsoft just signed a jaw-dropping agreement to purchase electricity from a nuclear fusion generator. Nuclear fusion, often called the Holy Grail of energy, is a potentially limitless source of clean energy that scientists have been chasing for the better part of a century.

Google needs to stop throwing good money after Bard

Posted by in categories: economics, robotics/AI

At its I/O developer conference, the search giant needs to rethink its AI strategy if it wants to catch Microsoft. The missing element? Experimentation.

Google has had a rough six months. Since ChatGPT launched last November — followed by the new Bing in February and GPT-4 in March — the company has failed to establish its AI credentials. Its own offering, the “experimental” chatbot Bard, compares poorly to rivals, and insider reports have portrayed a company in panic and disarray. Today, at its annual I/O conference, the company needs to convince the public (and shareholders) that it has a meaningful response. But to do that, it needs a new playbook.


AI outputs are increasingly defining the cultural moment — just not Google’s.

Humane’s new wearable AI demo is wild to watch — and we have lots of questions

Posted by in categories: mobile phones, robotics/AI, wearables

The demo is clever, questionably real, and prompts a lot of questions about how this device will actually work.

Buzz has been building around the secretive tech startup Humane for over a year, and now the company is finally offering a look at what it’s been building. At TED last month, Humane co-founder Imran Chaudhri gave a demonstration of the AI-powered wearable the company is building as a replacement for smartphones. Bits of the video leaked online after the event, but the full video is now available to watch.

The device appears to be a small black puck that slips into your breast pocket, with a camera, projector, and speaker sticking out the top.

China has its DrakeGPT moment as AI singer goes viral

Posted by in categories: internet, media & arts, robotics/AI

Mandopop singer Stefanie Sun has gone viral on Bilibili, China’s largest user-generated video streaming site. But the sudden revival of interest in Sun, who hasn’t released an album since 2017, comes not from the artist having another moment of genius.

The songs that have attracted millions of views on Bilibili feature Sun’s voice cloned by artificial intelligence, raising questions about copyright protection.

Reminiscing on the golden age of Mandarin pop music, tech-savvy Chinese internet users took the liberty of mimicking Sun’s voice using singing voice conversion, a deep learning method that lets a user deliver one person’s singing in another person’s voice, and swap it into a compilation of Mandpop classics.

Tiny Human Brain Tissue Organoids Can’t Be Legally Considered “a Person”

Posted by in categories: biotech/medical, law, neuroscience

Summary: Researchers proposed the need for a legal framework to guide the conversation on whether or not human brain organoids can be considered people.

Brain organoids are grown from stem cells in a lab, mimicking the growth and structure of real brains. However, they do not fulfill the requirements to be considered natural persons, according to the researchers.

The study explores the potential juridical personhood of human brain organoids, and whether they can be considered legal entities.

Forget hard drives and data centers, DNA is the future of data storage

So does that mean the internet will also crash by 2026? Well, it won’t if tech companies start using synthetic DNA instead of hard drives to store their data. You may not believe it, but according to Greef and his team, DNA strands can store large amounts of digital data, and in many ways, they have more advantages over modern-day data centers.

14 popular AI algorithms and their uses

Posted by in categories: information science, robotics/AI

Amid all the hype and hysteria about ChatGPT, Bard, and other generative large language models (LLMs), it’s worth taking a step back to look at the gamut of AI algorithms and their uses. After all, many “traditional” machine learning algorithms have been solving important problems for decades—and they’re still going strong. Why should LLMs get all the attention?

Before we dive in, recall that machine learning is a class of methods for automatically creating predictive models from data. Machine learning algorithms are the engines of machine learning, meaning it is the algorithms that turn a data set into a model. Which kind of algorithm works best (supervised, unsupervised, classification, regression, etc.) depends on the kind of problem you’re solving, the computing resources available, and the nature of the data.

In the next section, I’ll briefly survey the different kinds of machine learning and the different kinds of machine learning models. Then I’ll discuss 14 of the most commonly used machine learning and deep learning algorithms, and explain how those algorithms relate to the creation of models for prediction, classification, image processing, language processing, game-playing and robotics, and generative AI.
