Scientists have been studying tiny magnetic bits inside solids called spins. These spins are important because they could be the building blocks for future technologies that use quantum physics, like super-secure communication or super-fast computers.

Imagine you’re standing on a road where cars drive in both directions. Generally, the speed limit is the same whether you’re heading north or south. That’s exactly how light usually works in most systems, the “speed limit” stays the same no matter which way it’s going. This is called reciprocal control, the system treats both directions equally.

I’ll be honest, I have always thought ‘thought-experiments’ can never be visually demonstrated. And so, we would have to keep imagining intangible concepts in our minds, like, what happens to an object traveling at the speed of light, where time would seemingly stop and length would contract. However, a group of researchers in Austria did something unbelievable. They visually demonstrated the Terrell-Penrose effect, a phenomenon predicted all the way back in 1959 but never actually observed.

Researchers at MIT have built a small chip that can generate terahertz waves more effectively and more affordably than what’s currently out there. That’s huge, ‘cause terahertz waves sit between radio and infrared on the electromagnetic spectrum, so they can carry more data than radio waves and see through more materials than infrared light. This makes them a promising candidate for faster wireless communication, sharper medical imaging, better security scanners, and smarter environmental monitoring.

Have you ever watched two kids on swings, tied together by a spring? When one swings, the other starts moving too. That’s how scientists often imagine the relationship between light and matter at the quantum level. They call this a coupling , a way for two systems to influence each other.

Northwestern engineers have come up with something pretty wild, a pacemaker so small it can fit inside the tip of a syringe. Not only that, but it’s wireless, dissolves inside the body after doing its job, and can be injected without surgery.

James Gleick, one of my favorite science writers, wrote this famous quote in his book Chaos: Making a New Science: “IN THE MIND’S EYE, a fractal is a way of seeing infinity”.’ Doesn’t it also reflect how LLMs work? How? Just like fractals, these models take patterns, layer them and build something infinitely complex from simple rules. It’s like staring into a never-ending web of words, where meaning keeps unfolding the deeper we go.

Quantum criticality in metals is an exciting area of study where physics explores mysterious concepts. A new study in Nature Communications looks at a unique way to understand entanglement at a specific point called the Kondo destruction quantum critical point (QCP). Instead of using standard methods, the researchers focus on concepts like mutual information and quantum Fisher information (QFI) to explore how quantum connections change as they get closer to this transition.

Quantum computing is one of the most promising technological frontiers, but it comes with a major challenge, which is, maintaining the extreme cold temperatures that is required for qubits to function. Today’s quantum computers rely on dilution refrigerators, complex and highly specialized cooling systems that keep qubits operating near absolute zero. However, these systems are expensive, tough to maintain and don’t scale easily.

For decades, quantum networks have always been looked as a research curiosity than a practical technology. I personally imagined it to be a field of entangled particles, stretching across galaxy and the quantum connections in the field space enables telepathic communication, this is how I concluded, quantum entanglement happens.

I am a huge science fiction nerd and I see this genre as a window, a blueprint for the future. Since, it often imagines advanced tech, societal change, socio-economic possibilities, medicine, space exploration, even philosophy and ethics, before they become reality.

Researchers at Duke University have discovered the intricate molecular details of a material that might just be the key to next-generation rechargeable batteries. It’s called the superionic material. The compound displays both solid and liquid properties. How? It retains its solid structure, however, the ions within it move as freely as they would in a liquid.

AI agents are assisting people in making smarter choices, these tools are also helping in making tasks easier and enabling more personalized experiences across various domains. Their integration with external tools and APIs allows for real-time data analysis and automation of complex workflows. All this is possible because of a structured tech stack that integrates various layers, working in sync. The technology stack is like an entire football team, where goalkeepers, defenders, midfielders and strikers are the various layers, each with a unique function.

Disruption is the new normal! – This happens to be the current motif of the AI landscape. DeepSeek has posed some serious challenges to the conventional approach to AI model development. It has proved, at least looking at the current scenario, that there is no need for massive capital expenditures on training the LLMs. In fact, the advancement of AI isn’t just about the amount of data you put in, but how well you can prompt it! This reminds of a talk when asked where an Indian startup with limited…

An interesting development around quantum computing has surfaced. We all know that these quantum systems require super cold temperature to operate at their optimal performance. Why? Well, the fundamental blocks of quantum computers, which are, the qubits cannot function in regular temperature. For reliable quantum computation, these quantum systems require extremely low temperatures as they are highly sensitive to their surroundings, in fact, even a tiny disturbance by weak electromagnetic interference can cause errors in their system.
