My musings on physics and technologies

In the world of quantum physics, where the rules of reality seem to bend, scientists at Los Alamos National Laboratory have achieved a significant breakthrough. They've managed to create a continuous stream of circularly polarized single photons—particles of light—that hold immense potential for revolutionizing quantum information and communication technologies. This feat is made even more remarkable by the fact that it doesn't require the application of an external magnetic field or complex nanoscale structures. Let's dive into this exciting discovery and understand its implications. Unveiling Quantum Light Emitters Imagine being able to generate particles of light that are not only single and steady but also possess a specific spin, known as circular polarization. This is precisely what the researchers at Los Alamos National Laboratory have accomplished—a milestone that could propel quantum cryptography and communication into new dimensions. Typically, achieving circularl

In the previous blogs we discussed the death of various sized stars and concluded that the death of massive stars results in the birth of two of the most extreme bodies in our universe -  neutron stars and black holes . We concluded with the discussion of neutron stars in the previous blog and today we will discuss the most extreme body in our universe - the black hole... You may remember that the death of supermassive stars can result in the formation of either neutron stars or black holes.  An illustration of a neutron star When   s tars  four to eight times as massive as the sun explode in a violent supernova, their outer layers can blow off in an often-spectacular display, leaving behind a small, dense core that continues to collapse. Gravity presses the material in on itself so tightly that protons and electrons combine to make neutrons forming a neutron star. An artist's illustration of a supernova What happens after the explosion depends on the mass of the neutron star. If i

In a world where computers crunch numbers at lightning speed and provide instant recall of trivia, it's easy to overlook the marvel of the human brain. Our brains process intricate information seamlessly, distinguishing faces and comprehending complex scenes effortlessly. But what if we could infuse computers with brain-like efficiency while minimizing energy consumption? The groundbreaking research by the Quantum Materials for Energy Efficient Neuromorphic Computing (Q-MEEN-C) consortium, spearheaded by the University of California San Diego, is unlocking this extraordinary potential. source : UCSD today Unraveling the Brain's Secrets with Quantum Materials Powered by a vision of computers that mimic the remarkable prowess of our brains, the Q-MEEN-C consortium is at the forefront of a technological revolution. Their journey began by exploring non-local interactions within quantum materials—a phenomenon where actions in one part of a system impact distant regions. This behavio
