The First Steps Toward a Quantum Brain: An Intelligent Material That Learns by Physically Changing Itself

Posted by in categories: particle physics, quantum physics, robotics/AI

An intelligent material that learns by physically changing itself, similar to how the human brain works, could be the foundation of a completely new generation of computers. Radboud physicists working toward this so-called “quantum brain” have made an important step. They have demonstrated that they can pattern and interconnect a network of single atoms, and mimic the autonomous behavior of neurons and synapses in a brain. They report their discovery in Nature Nanotechnology.

Considering the growing global demand for computing capacity, more and more data centers are necessary, all of which leave an ever-expanding energy footprint. “It is clear that we have to find new strategies to store and process information in an energy efficient way,” says project leader Alexander Khajetoorians, Professor of Scanning Probe Microscopy at Radboud University.

“This requires not only improvements to technology, but also fundamental research in game changing approaches. Our new idea of building a ‘quantum brain’ based on the quantum properties of materials could be the basis for a future solution for applications in artificial intelligence.”

Making Of A Neuromorphic Synchronization Circuit Using Quantum Metaheuristics

Posted by in categories: computing, quantum physics, space

In this video I show how I made a self-organisating network of Kuramoto-style oscillators in a system undergoing metaheuristic-guided synchronization. There are also ways to visually demonstrate this with relatively simple hardware, such as using modified microelectronics, controlled using microcontroller circuits.

In this project, which I have dubbed “Feynman’s Quantum Fireflies” I program individual systems of oscillators which display discontinuous pas coupling which can be implemented in a network of transceiver circuits. Using the Path Integral Approach is one way to understand how the system behaves like a quantum thermal bath.

A New Kind of Light in the Universe? “Super-Planckian” Material Emits Light That Exceeds Limits of Natural Law

Posted by in categories: energy, quantum physics

Could there be a new kind of light in the universe? Since the late 19th century, scientists have understood that, when heated, all materials emit light in a predictable spectrum of wavelengths. Research published today in Nature Scientific Reports presents a material that emits light when heated that appears to exceed the limits set by that natural law.

In 1900, Max Planck first mathematically described a pattern of radiation and ushered in the quantum era with the assumption that energy can only exist in discrete values. Just as a fireplace poker glows red hot, increasing heat causes all materials to emit more intense radiation, with the peak of the emitted spectrum shifting to shorter wavelengths as heat rises. In keeping with Planck’s Law, nothing can emit more radiation than a hypothetical object that absorbs energy perfectly, a so-called “blackbody.”

The new material discovered by Shawn Yu Lin, lead author and a professor of physics at Rensselaer Polytechnic Institute, defies the limits of Planck’s law, emitting a coherent light similar to that produced by lasers or LEDs, but without the costly structure needed to produce the stimulated emission of those technologies. In addition to the spectroscopy study just published in Nature Scientific Reports, Lin previously published an imaging study in IEEE Photonics Journal. Both show a spike in radiation at about 1.7 microns, which is the near-infrared portion of the electromagnetic spectrum.

Quantum tunneling in graphene advances the age of terahertz wireless communications

Posted by in categories: biotech/medical, quantum physics, security

Scientists from MIPT, Moscow Pedagogical State University and the University of Manchester have created a highly sensitive terahertz detector based on the effect of quantum-mechanical tunneling in graphene. The sensitivity of the device is already superior to commercially available analogs based on semiconductors and superconductors, which opens up prospects for applications of the graphene detector in wireless communications, security systems, radio astronomy, and medical diagnostics. The research results are published in Nature Communications.

ABS Signs Teleport Deal with Telemedia

Posted by in categories: biotech/medical, computing, engineering, quantum physics

ABS is partnering with Telemedia, a broadcasting and teleport service provider in South Africa, to improve its service offerings to customers in the Middle East and Africa region (MEA). ABS announced Monday that the company will gain access to a full suite of telecom services provided by Telemedia at its Johannesburg teleport. Telemedia will provide teleport fiber connectivity, data center hosting, and satellite uplink capabilities.

Telemedia said the partnership enables the company to further expand its broadcast and satellite connectivity services in the MEA.

“Our collaboration with Telemedia reinforces and strengthens our presence in the MEA and provides an extension to our global connectivity network,” Ron Busch, ABS’ EVP Engineering and Operations said. “[Telemedia’s] infrastructure offering with a solid track record, excellent customer support and can-do attitude during the COVID-19 pandemic shows its commitment to excellent customer service.”
