Long live superconductivity! Short flashes of light with sustaining impact

Posted by in category: quantum physics

Superconductivity—the ability of a material to transmit an electric current without loss—is a quantum effect that, despite years of research, is still limited to very low temperatures. Now a team of scientists at the MPSD has succeeded in creating a metastable state with vanishing electrical resistance in a molecular solid by exposing it to finely tuned pulses of intense laser light. This effect had already been demonstrated in 2016 for only a very short time, but in a new study the authors of the paper have shown a far longer lifetime, nearly 10.000 times longer than before. The long lifetimes for light-induced superconductivity hold promise for applications in integrated electronics. The research by Budden et al. has been published in Nature Physics.

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.”

Inductance based on a quantum effect has the potential to miniaturize inductors

Posted by in categories: mobile phones, quantum physics

Mobile-phone chargers and other devices could become much smaller after an all-RIKEN team of physicists successfully shrunk an electrical component known as an inductor to microscale dimensions using a quantum effect.

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.
