Quantum Leap — Harvard Scientists Use Sound To Test Devices, Control Qubits

Posted by in categories: mapping, mobile phones, quantum physics, satellites

Acoustic resonators, found in devices like smartphones and Wi-Fi systems, degrade over time with no easy way to monitor this degradation. Researchers from Harvard SEAS and Purdue University have now developed a method using atomic vacancies in silicon carbide to measure the stability of these resonators and even manipulate quantum states, potentially benefiting accelerometers, gyroscopes, clocks, and quantum networking.

Acoustic resonators are everywhere. In fact, there is a good chance you’re holding one in your hand right now. Most smartphones today use bulk acoustic resonators as radio frequency filters to filter out noise that could degrade a signal. These filters are also used in most Wi-Fi and GPS

GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on or near the Earth’s surface. It consists of a network of satellites, ground control stations, and GPS receivers, which are found in a variety of devices such as smartphones, cars, and aircraft. GPS is used for a wide range of applications including navigation, mapping, tracking, and timing, and has an accuracy of about 3 meters (10 feet) in most conditions.

Using sound to test devices, control qubits

Posted by in categories: mobile phones, quantum physics

Acoustic resonators are everywhere. In fact, there is a good chance you’re holding one in your hand right now. Most smart phones today use bulk acoustic resonators as radio frequency filters to filter out noise that could degrade a signal. These filters are also used in most Wi-Fi and GPS systems.

Acoustic resonators are more stable than their electrical counterparts, but they can degrade over time. There is currently no easy way to actively monitor and analyze the degradation of the material quality of these widely used devices.

Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with researchers at the OxideMEMS Lab at Purdue University, have developed a system that uses atomic vacancies in to measure the stability and quality of acoustic resonators. What’s more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.

Google antitrust case: Will Apple create its own search engine?

Posted by in categories: computing, mobile phones

The trial has revealed that Google was concerned about losing its monopoly to Spotlight, an in-house search engine made by Apple.

Google and Apple compete on several fronts – operating systems, email, app stores, cloud computing, and photo apps. While Google leads in the market share of its phone operating system, Apple boasts of a line of very cool hardware tech. But they remain partners in one key area, which is also currently in the eye of the storm.

Google pays Apple for its search engine to be the default selection on iPhones. Its parent company, Alphabet, pays the iPhone maker upwards of $20 billion annually as part of the deal. In 2016, Apple reportedly was presented with a lucrative billion-dollar offer by Microsoft to replace Google with Bing in its phones. But Apple didn’t budge.

Apple’s $1 billion standoff against AI-rivals Microsoft, Google, OpenAI

Posted by in categories: mobile phones, robotics/AI

No AI announcements expected at Apple event on Monday.

Apple is reportedly spending a billion dollars a year in a major push for artificial intelligence. Over the last year, the AI boom has seen many of its tech adversaries investing millions and billions of dollars into large language models (LLMs) and conversational platforms.

Although the iPhone maker is hush about what is cooking in its AI laboratory, Interesting Engineering reported earlier that the company may be looking to revamp Siri with generative AI capabilities. Much like how OpenAI’s ChatGPT (Plus and Enterprise) can now generate content from voice commands, iPhone users could use Siri similarly.

Motorola Teases Flexible Phone You Wear Like A Bracelet

Posted by in category: mobile phones

Motorola unveiled a flexible phone with an adaptive display that you can wear like a bracelet or watch yesterday at Lenovo Tech World ‘23 in Austin. The full HD phone can be bent into multiple shapes, including one that props it up on a table or desk for viewing, or a full U-shaped bracelet that straps on to your wrist.

The phone offers a 6.9 display when flat and a 4.6 display when curved to sit on a flat surface like a bedside clock or a standalone viewing screen. The flexible screen appears to be paired with a fabric backing, unusual in a smartphone. The phone does not just friction-fit to your wrist, which would be likely to slip off with movement, but magnetically clings to an… More.

IBM has made a new, highly efficient AI processor

Posted by in categories: mobile phones, robotics/AI

As the utility of AI systems has grown dramatically, so has their energy demand. Training new systems is extremely energy intensive, as it generally requires massive data sets and lots of processor time. Executing a trained system tends to be much less involved—smartphones can easily manage it in some cases. But, because you execute them so many times, that energy use also tends to add up.

Fortunately, there are lots of ideas on how to bring the latter energy use back down. IBM and Intel have experimented with processors designed to mimic the behavior of actual neurons. IBM has also tested executing neural network calculations in phase change memory to avoid making repeated trips to RAM.

Now, IBM is back with yet another approach, one that’s a bit of “none of the above.” The company’s new NorthPole processor has taken some of the ideas behind all of these approaches and merged them with a very stripped-down approach to running calculations to create a highly power-efficient chip that can efficiently execute inference-based neural networks. For things like image classification or audio transcription, the chip can be up to 35 times more efficient than relying on a GPU.

D-ID’s newest app uses AI to make videos from photographs

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

D-ID, the Tel Aviv-based startup best known as the tech behind those viral videos of animated family photos, is bringing its AI video technology to a new mobile app, launching today. Originally available as a web platform, D-ID’s Creative Reality Studio allows users to upload a still image and script and then turn that into an AI-generated video. The technology can be used to create digital representations of themselves, historical figures, fictional characters, presenters or brand ambassadors.

Early use cases the company had been targeting involved corporate training and education, internal and external communication from companies, and product marketing and sales, TechCrunch previously reported.

Now available on mobile, users will download the D-ID app from the App Store or Google Play and then create an account or log in, if already registered. On the selection screen, you can either pick a premade “digital person” that D-ID provides or upload an image from your phone’s photo library. You’ll then enter the text you want the digital person to say, choosing from 119 languages, as well as pick between male and female voice options. You can also choose the tone of the speech — like cheerful, excited, friendly, hopeful, newscast, sad, shouting, terrified, unfriendly, whispering and others.

Hologram Zoo Is Real And Signals The Future

Posted by in categories: 3D printing, holograms, mobile phones

The number of Star Trek sci-fi technology that ultimately became real-life tech never ceases to amaze. The series inspired the development of touchscreens, communicators became mobile phones, PAADs became tablets, replicators became 3D printing, and now holodecks are becoming virtual and augmented realities (VRs and ARs). And while fully immersive environments like the holodeck still remain in the realm of sci-fi, a recent report from BBC on a hologram zoo indicates that the future isn’t so far-fetched when it comes to immersive holographic.

The holograms use a new depth technology that not only makes the animals seem big but makes them visible as 3D objects rather than suspended 2D images.

According to the report, the visitors of Australia’s Hologram Zoo, which opened earlier this year, can dodge stampeding elephants, peer into the gaping jaws of a hippopotamus, pet-friendly giraffes, and witness more than 50 lifelike displays from dinosaurs to gorillas—all crafted from concentrated beams of light.
