AI Needs Enormous Computing Power. Could Light-Based Chips Help?

Posted by in category: robotics/AI

The International Energy Agency predicts that artificial intelligence will consume 10 times as much energy in 2026 as it did in 2023.


Optical neural networks, which use photons instead of electrons, have advantages over traditional systems. They also face major obstacles.

A model outlining the microscopic origin of black hole entropy

Posted by in categories: cosmology, physics

Black holes are intriguing astronomical objects that have a gravitational pull so strong that it prevents any object and even light from escaping. While black holes have been the topic of numerous astrophysical studies, their origins and underlying physics remain largely a mystery.

Scientists discover single atom defect in 2D material can hold quantum information at room temperature

Posted by in categories: particle physics, quantum physics

Scientists have discovered that a “single atomic defect” in a layered 2D material can hold onto quantum information for microseconds at room temperature, underscoring the potential of 2D materials in advancing quantum technologies.

The defect, found by researchers from the Universities of Manchester and Cambridge using a thin material called (hBN), demonstrates spin coherence—a property where an electronic spin can retain —under ambient conditions. They also found that these spins can be controlled with light.

Up until now, only a few have been able to do this, marking a significant step forward in quantum technologies.

NA64 uses the high-energy SPS muon beam to search for dark matter

Posted by in categories: cosmology, particle physics

The NA64 experiment started operations at CERN’s SPS North Area in 2016. Its aim is to search for unknown particles from a hypothetical “dark sector.” For these searches, NA64 directs an electron beam onto a fixed target. Researchers then look for unknown dark sector particles produced by collisions between the beam’s electrons and the target’s atomic nuclei.

Iso-propagation vortices: Optical multiplexing for unprecedented information capacity

Posted by in category: futurism

The future of optical communications just got brighter. In a development reported in Advanced Photonics, researchers from Nanjing University have introduced iso-propagation vortices (IPVs), a novel concept that offers a solution to a long-standing challenge faced by scientists and engineers: how to increase information processing capacity while overcoming the limitations of traditional vortex beams.

Seeing the color of entangled photons in molecular systems

Posted by in category: particle physics

Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way particles of light called photons interact with matter. These classical spectroscopy techniques include one-photon absorption (OPA) and two-photon absorption (TPA).

Expanding on the fundamental principles of liquid movement

Posted by in categories: electronics, nanotechnology

From the rain drops rolling down your window, to the fluid running through a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces is a heavily researched subject, where new discoveries can have profound effects in the fields of energy conversion technology, electronics cooling, biosensors, and micro-/nano-fabrications.

Researchers develop entangled photon pairs in integrated silicon carbide for first time

Posted by in categories: particle physics, quantum physics

Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly magical process called teleportation can share information between different far-flung quantum systems.
