Artificial brain networks simulated with new quantum materials

Posted by in categories: biotech/medical, quantum physics, robotics/AI, supercomputing

Isaac Newton’s groundbreaking scientific productivity while isolated from the spread of bubonic plague is legendary. University of California San Diego physicists can now claim a stake in the annals of pandemic-driven science.

A team of UC San Diego researchers and colleagues at Purdue University have now simulated the foundation of new types of artificial intelligence computing devices that mimic brain functions, an achievement that resulted from the COVID-19 pandemic lockdown. By combining new supercomputing materials with specialized oxides, the researchers successfully demonstrated the backbone of networks of circuits and devices that mirror the connectivity of neurons and synapses in biologically based neural networks.

The simulations are described in the Proceedings of the National Academy of Sciences (PNAS).

AMD teleportation patent could be ‘Zen moment’ for quantum computing

Posted by in categories: computing, quantum physics

The patent in question is for a system that would use quantum teleportation in order to boost a quantum computer’s reliability, while at the same time reducing the number of qubits required for a given calculation. This “teleportation” technology would help solve scaling issues and calculation errors that arise from system instability.

One of the main issues behind quantum development is once you start pushing the pedal to the metal, there are major issues when it comes to scalability and stability. Quantum computing is far different to the 0s and 1s of traditional technology, so AMD’s new teleportation patent is quite an important step towards solving that issue.

Black holes just got much more complicated thanks to quantum pressure

Posted by in categories: cosmology, quantum physics

Black holes were once thought not to have pressure, but a new set of quantum calculations has found that they may have some at their edges, which was completely unexpected.

Quantum mechanics and our part in creating reality

Posted by in categories: biotech/medical, mobile phones, quantum physics

A new interpretation of quantum mechanics sees agents as playing an active role in the creation of reality. Blake Stacey outlines the case for QBism and its radical potential.

The pandemic shut down our university when I was in the middle of giving a lecture. We had been anticipating the possibility for a few days, but it was still impeccable timing. I finished my spiel, out came the phones, and suddenly we weren’t going to see each other post-spring break after all. For the rest of the term, I did what so many teachers found themselves doing: gamely trying to soldier on. I scrounged and borrowed a whiteboard, easel and webcam, set myself up in the nicest light the house had to offer, and did my best to convey graduate-level physics to an audience of tiny rectangles. And like so many other teachers, I learned there’s nothing like a radical change of circumstances for driving one to re-evaluate what the essential ideas of a subject must be.

Fast tool developed for quantum computing and communication

Posted by in categories: computing, quantum physics

Isaac Nape, an emerging South African talent in the study of quantum optics, is part of a crack team of Wits physicists who led an international study that revealed the hidden structures of quantum entangled states. The study was published in the renowned scientific journal, Nature Communications, on Friday, 27 August 2021.

Nape is pursuing his Ph.D. at Wits University and focuses on harnessing structured for high dimensional information encoding and decoding for use in .

Earlier this year he scooped up two awards at the South African Institute of Physics (SAIP) conference to add to his growing collection of accolades in the field of optics and photonics. He won the award for “Best Ph.D. oral presentation in applied physics,” and jointly won the award for “Best Ph.D. oral presentation in photonics.”
