The end of hacking? How Isro and DRDO are building an unhackable quantum future
In a world increasingly reliant on digital infrastructure, securing data is no longer a luxury — it is a necessity. While today's encryption systems rely on mathematical complexity, the cybersecurity of tomorrow will be grounded in the laws of quantum the heart of this revolution is quantum entanglement, a phenomenon Albert Einstein famously described as 'spooky action at a distance.'advertisementIndia, through the collaborative efforts of Isro and DRDO, is taking bold steps to harness this concept and build hack-proof quantum communication systems that could secure everything from satellite signals to financial transactions. When you log into your bank account or send a private message, your password acts as a lock protected by complex mathematical algorithms. Even the most powerful supercomputer—like El Capitan at the Lawrence Livermore National Laboratory, capable of 1.742 quintillion calculations per second—would take centuries to break this the looming threat is real: fully developed quantum computers could solve these puzzles in seconds. This means emails, bank transactions, and national secrets could be exposed instantly if we don't transition to quantum-secure communication. India currently lags in satellite-based execution.

This is the promise of Quantum Key Distribution (QKD). When two particles, such as photons, are entangled, their states remain linked regardless of distance. It's like rolling one magical die on Earth and seeing the same result on another at the edge of the a quantum setting, two users — commonly called Alice and Bob — exchange encryption keys using quantum particles. If a third party, Eve, tries to intercept the key, the quantum state is disturbed, immediately alerting the users to the transmitted through air, fiber optics, or satellites, quantum-secure communication ensures that any eavesdropping attempt is not just detectable — but automatically shuts down the process. With this technology, India is paving the way for a future where data is truly QUANTUM SECURITYThere are several ways to implement quantum-secure communication: through optical fibers, free-space air links, and increasingly, satellite-based quantum communication is well-suited for secure links within cities, while free-space communication is used for rooftop or mobile the real game-changer is satellite-based quantum communication, where satellites transmit quantum keys across hundreds—or even thousands—of is making significant strides in this domain. ISRO recently demonstrated entanglement-based quantum-secure communication over a 300-meter distance, where encrypted video was successfully decrypted using secure quantum keys transmitted via photons and lasers. In another breakthrough, DRDO, in collaboration with IIT Delhi, achieved hack-proof communication over a distance of more than 1 achievements are not only technologically sophisticated but also strategically vital for national defense and critical infrastructure GLOBAL SCENARIOGlobally, China leads the race with its Micius satellite, enabling secure Quantum communication over 1,200 kilometres, followed by pioneering urban experiments in Europe and the India currently lags in satellite-based execution, its dual-pronged civil-military approach gives it a unique 1 km free-space and 100 km fiber demonstrations are impressive but lag behind China's satellite Isro has already outlined plans for space-based quantum communication, and DRDO is targeting secure battlefield and rural deployment.

AMD supercomputers lead Top500 rankings with record exaflops
El Capitan and Frontier, both powered by AMD processors and accelerators, have retained the top two positions on the latest Top500 list of the world's most powerful supercomputers. Supercomputing leadership The recently released Top500 rankings show that El Capitan, based at Lawrence Livermore National Laboratory, remains the fastest system globally, registering a High Performance Linpack (HPL) score of 1.742 exaflops. Frontier, situated at Oak Ridge National Laboratory, holds the second position with an HPL result of 1.353 exaflops. Both supercomputers were constructed by HPE and utilise AMD hardware at their core. El Capitan uses AMD Instinct MI300A accelerated processing units (APUs), integrating CPU and GPU functionality within a single package, aimed at supporting large-scale artificial intelligence and scientific workloads. Frontier leverages AMD EPYC CPUs alongside AMD Instinct MI250X GPUs for a variety of advanced computational research needs, including modelling in energy, climate, and next-generation artificial intelligence. Broader AMD presence AMD technologies now underpin 172 supercomputing systems out of the 500 included in the latest Top500 list. This figure represents more than a third of all the high-performance systems measured. Notably, 17 new systems joined the list this year running on AMD processors, five of which use the latest 5th Gen AMD EPYC architecture. The expanded presence spans institutions such as the University of Stuttgart's High-Performance Computing Center, where the Hunter system is powered by AMD Instinct MI300A APUs; the University of Hull's Viper supercomputer; and Italy's new EUROfusion Pitagora system at CINECA, powered by 5th Gen AMD EPYC CPUs. Performance and efficiency In addition to sheer computational power, AMD's showing on the Top500 list extends to energy efficiency. According to the most recent Green500 list, 12 of the 20 most energy-efficient supercomputers globally use AMD EPYC processors and AMD Instinct accelerators. El Capitan and Frontier ranked 26th and 32nd respectively on the Green500 index, reflecting their performance-per-watt capabilities given their computing output. This was echoed in alternative benchmarks. On the HPL-MxP test, which measures mixed-precision computing suited for artificial intelligence workloads, El Capitan debuted at the top, reaching 16.7 exaflops, with Frontier in third place and LUMI, another AMD system, in fourth. The HPCG (High-Performance Conjugate Gradient) test, a complementary performance metric for scientific applications, saw El Capitan post the highest benchmark score of 17.4 petaflops, marking it out for memory bandwidth enabled by the Instinct MI300A architecture. Institutional perspectives "From El Capitan to Frontier, AMD continues to power the world's most advanced supercomputers, delivering record-breaking performance and leadership energy efficiency," said Forrest Norrod, Executive Vice President and General Manager, Data Center Solutions Group, AMD. "With the latest Top500 list, AMD not only holds the top two spots but now powers 172 of the world's fastest systems—more than ever before—underscoring our accelerating momentum and the trust HPC leaders place in our CPUs and GPUs to drive scientific discovery and AI innovation." Rob Neely, Associate Director for Weapon Simulation and Computing at Lawrence Livermore National Laboratory, described the impact of El Capitan: "El Capitan is a transformative national resource that will dramatically expand the computational capabilities of the NNSA labs at Livermore, Los Alamos and Sandia in support of our national security and science missions. With AMD's advanced APU architecture, we can now perform simulations with the precision and confidence we set as a goal 15 years ago, when the path to exascale was difficult to foresee. As a bonus, this platform is a true 'two-fer' - an HPC and AI powerhouse that will fundamentally reshape how we fulfill our mission." Future direction The distinction on the Top500 and Green500 lists coincides with a broader shift within high performance computing, as artificial intelligence and traditional HPC workloads increasingly converge. AMD's presence in the sector demonstrates demand for scalable and efficient compute platforms amid growing power requirements for data-intensive scientific and industrial workloads. The results also indicate the use of a portfolio that includes CPUs, GPUs, and APUs to accelerate developments across domains ranging from nuclear safety and climate modelling, to training large language models and generative artificial intelligence inference.

Yosemite Bans Large Flags From El Capitan, Criminalizing Protests
It is one of America's most majestic and recognizable landmarks, having beckoned Teddy Roosevelt, Ansel Adams and, more recently, protesters. From the granite walls of El Capitan in California's Yosemite National Park, demonstrators have draped large flags and banners several times in the past year in protest of a number of issues, including the Israel-Hamas war and various Trump administration policies. There was one symbolizing transgender pride, another saying 'Stop the Genocide' and an upside-down American flag, which represents distress. Now, the federal government seemingly wants to keep the famous rock formation a blank slate. It has outlawed large flags, banners and signs from El Capitan and most of the park altogether. The ban appears to have been formalized last month by Yosemite's acting superintendent, Raymond McPadden, in a Park Service compendium of regulations dated May 20. The rule tracks with a series of punitive actions by the Trump administration against some critics of its immigration policies and Palestinian sympathizers. Want all of The Times? Subscribe.
