Skip Zoom? Holographic tech allows you to ‘beam’ into your next meeting

Posted by in categories: health, holograms

The hologram device has been announced as a CES 2023 Innovation Awards Honoree. That’s two times in a row.

Zoom-like webcam chats could be going the way of the dodo, a new holographic technology is making waves to bridge the gap between the real and virtual worlds.

You’ll Soon Be Able To Run Holograms On Your Smartphone

Posted by in categories: computing, holograms, mobile phones

I had many ideas on how to improve Twitter, and a communication paradigm was one. The iPhone changed phones, and was a device. Twitter has no device to add to its portfolio. People have no desire to add products to Twitter portfolio to boost revenues. iPhone revenue surpassed computers, therefore it is very easy for Twitter to develop its portfolio to include better more reliable forms of revenue than advertising. A device can make a lot of money if it is a “paradigm” like an iPhone that completely changed our understanding of what a phone can be.

In 1943, Thomas Watson, the president of IBM, famously predicted the world market for computers would top out at “maybe five” of the machines. He was wrong – you likely have more than that in your own house, let’s face it – but at the time, it made sense. After all, if computers were still gigantic, vacuum-tube-powered addition machines, you probably wouldn’t want more than about five either.

It’s a similar story with holograms. Even back in the 1990s, more than 40 years after Dennis Gabor first came up with the idea of using wavefront interference to reconstruct images in three dimensions, science fiction was still assuming the need for entire decks and suites to power our holographic adventures.

This bizarre yet fascinating laser can write in the air has been created by researchers at the Hongtuo Joint Laboratory in Wuhan, China. This pen might possibly be a gateway to a cutting-edge hologram technology.

China Shows Off High-Powered Laser That Can ‘Write’ In The Air

Posted by in categories: holograms, particle physics

Movie plots often use holograms to give the scene a scientific or cooler essence. However, researchers have made these futuristic scenes a reality. According to reports, Scientists in China showcased a laser that can create Chinese characters out of thin air.

Although lasers often have a long-range, you can only see them when the light lands on a surface. However, dust particles made an exception. But this is entirely different and looks like something out of a sci-fi movie.

Scientists have already used lasers to create a range of optical illusions. However, it required mediums like dust and clouds to do so. But according to reports, with the new device, researchers are able to draw patterns using ultra-short laser pulses.

Theory claims to offer the first ‘evidence’ our Universe is a hologram

While theories of holographic universes have been around since the 1990s, the latest study, published in the journal Physical Review Letters, contains the first proof, the researchers say.

To find the ‘evidence’, the researchers developed models of the holographic Universe that can be tested by peering back in time as far as 13 billion years, at the furthest reaches of the observable Universe. These models depend on the theory of quantum gravity, a theory that challenges the accepted version of classical gravity. The holographic principle says gravity comes from thin, vibrating strings which are all holograms of a flat, 2D Universe.

Edible holograms could decorate or even authenticate food

Year 2021 face_with_colon_three

Remember back in the mid-80s, when mass-produced holograms were such a big deal? Since then, they’ve become common on credit cards, currency and other items. Now, thanks to new research, you can actually eat the things.

First of all, why would anyone want an edible hologram? Well, along with simply being used for decorative purposes, they could conceivably also serve to show that a food item hasn’t been tampered with, or to display its name and/or ingredients in a way that proves it isn’t a counterfeit product.

Physicists Create a Holographic Wormhole Using a Quantum Computer

Posted by in categories: cosmology, holograms, quantum physics, robotics/AI

Physicists have purportedly created the first-ever wormhole, a kind of tunnel theorized in 1935 by Albert Einstein and Nathan Rosen that leads from one place to another by passing into an extra dimension of space.

The wormhole emerged like a hologram out of quantum bits of information, or “qubits,” stored in tiny superconducting circuits. By manipulating the qubits, the physicists then sent information through the wormhole, they reported today in the journal Nature.

The team, led by Maria Spiropulu of the California Institute of Technology, implemented the novel “wormhole teleportation protocol” using Google’s quantum computer, a device called Sycamore housed at Google Quantum AI in Santa Barbara, California. With this first-of-its-kind “quantum gravity experiment on a chip,” as Spiropulu described it, she and her team beat a competing group of physicists who aim to do wormhole teleportation with IBM and Quantinuum’s quantum computers.”

Researchers develop programmable optical device for high-speed beam steering

Posted by in category: holograms

In a scene from “Star Wars: Episode IV—A New Hope,” R2D2 projects a three-dimensional hologram of Princess Leia making a desperate plea for help. That scene, filmed more than 45 years ago, involved a bit of movie magic—even today, we don’t have the technology to create such realistic and dynamic holograms.

Generating a freestanding 3D hologram would require extremely precise and fast control of light beyond the capabilities of existing technologies, which are based on liquid crystals or micromirrors.

An international group of researchers, led by a team at MIT, has spent more than four years tackling this problem of high-speed optical beam forming. They have now demonstrated a programmable, wireless device that can control light, such as by focusing a beam in a specific direction or manipulating the light’s intensity, and do it orders of magnitude more quickly than commercial devices.

Black Holes and Holograms: A New Theory That Changes Our Understanding of the Universe

Posted by in categories: cosmology, holograms, quantum physics

Confusing? It may sound so, but it isn’t actually. What Benini and Milan have done is apply the theory of the holographic principle to black holes. In this way, their mysterious thermodynamic properties have become more understandable: by focusing on predicting that these bodies have high entropy and looking at them in terms of quantum mechanics, which allows us to describe them as a hologram: they have two dimensions, in which gravity disappears, but they reproduce an object in three dimensions.

But there’s more. Much more.

According to the authors of the new studies, this is only the first step towards a deeper understanding of these cosmic bodies and the properties that characterize them when quantum mechanics intersects with general relativity.
