Technology advance paves way to more realistic 3D holograms for virtual reality and more      (via sciencedaily.com)     Original source 

Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.

Absolute zero in the quantum computer      (via sciencedaily.com)     Original source 

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.

New chip design to provide greatest precision in memory to date      (via sciencedaily.com) 

Everyone is talking about the newest AI and the power of neural networks, forgetting that software is limited by the hardware on which it runs. But it is hardware become 'the bottleneck.' New collaborators might change that. They believe that they have developed a new type of chip with the best memory of any chip thus far for edge AI (AI in portable devices). To put it in context, right now, ChatGPT is running on a cloud. The new innovation, followed by some further development, could put the power of a mini version of ChatGPT in everyone's personal device. It could make such high-powered tech more affordable and accessible for all sorts of applications.

Can a solid be a superfluid? Engineering a novel supersolid state from layered 2D materials      (via sciencedaily.com)     Original source 

Physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. This counterintuitive quantum material simultaneously forms a rigid crystal, and yet at the same time allows particles to flow without friction, with all the particles belong to the same single quantum state.

First silicon integrated ECRAM for a practical AI accelerator      (via sciencedaily.com) 

The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.

New type of entanglement lets scientists 'see' inside nuclei      (via sciencedaily.com) 

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.

Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator      (via sciencedaily.com) 

Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.
