Breakthrough for the #quantum internet: For the first time a major telco provider has successfully conducted entangled photon experiments - on its own infrastructure. ➡️ 30 kilometers, 17 days, 99 per cent fidelity. Our teams at T-Labs have successfully transmitted entangled photons over a fiber-optic network. Over a distance comparable to travelling from Berlin to Potsdam. The system automatically compensated for changing environmental conditions in the network.   Together with our partner Qunnect we have demonstrated that quantum entanglement works reliably. The goal: a quantum internet that supports applications beyond secure point-to-point networks. Therefore, it is necessary to distribute the types of entangled photons. The so-called qubits, that are used for #QuantumComputing, sensors or memory. Polarization qubits, like the ones used for this test, are highly compatible with many quantum devices. But: they are difficult to stabilize in fibers.   From the lab to the streets of Berlin: This success is a decisive step towards the quantum internet. 🔬 It shows how existing telecommunications infrastructure can support the quantum technologies of tomorrow. This opens the door to new forms of communication.   Why does this matter for people and society?   🗨️ Improved communications: The quantum internet promises faster and more efficient long-distance communications. 🔐 Maximum security: Entanglement can be used in quantum key distribution protocols. Enabling ultra-secure communication links for enterprises and government institutions 💡Technological advancement: high-precision time synchronization for satellite networks and highly accurate sensing in industrial IoT environments will need entanglement.   Developing quantum technologies isn’t just a technical challenge. A #humancentered approach asks how these systems can be built to serve real needs and be part of everyday infrastructure. With 2025 designated as the International Year of Quantum Science and Technology, now is the time to move from research to readiness.

Quantum readiness is less about sudden disruption and more about cultivating skills, forging collaborations, and aligning strategies with evolving standards, so that businesses can gradually integrate these technologies into their long-term transformation paths. We should see quantum computing as a journey that requires methodical preparation. Finance, logistics, chemistry, and cybersecurity are already experimenting with hybrid models that combine classical and quantum systems. These early steps show that the transition will not happen overnight, but through structured phases of learning and integration. The priority for leaders is to identify processes where quantum can create measurable improvements. This means feasibility studies, pilots, and a roadmap that integrates quantum into IT environments in a sustainable way. At the same time, teams need training in principles, tools, and algorithms, because without this foundation, the technology remains an abstract concept. Collaboration is another essential layer. Partnerships with research hubs, vendors, and cloud providers open access to quantum resources that would otherwise remain out of reach. Alongside this, governance and security must advance with post-quantum standards, ensuring compliance and ethics are never secondary. The real challenge is continuous adaptation. Regulations and technologies will evolve, and strategies must remain flexible. This long-term perspective will define the organizations that are prepared to grow with the next wave of innovation. #QuantumComputing #DigitalTransformation #FutureOfWork

Excited about bringing #quantumcomputing to the #datacenter, but not sure how to proceed? In this first article in Data Center Dynamics we lay out three key steps to integrate this cutting edge technology into the data center, and discuss the critical choices a customer must address along the way.

Can STRATEGY learn anything from QUANTUM MECHANICS? Quantum mechanics offers valuable insights for strategic leadership in today's complex and uncertain business environment. Here's how we can apply quantum principles to enhance our leadership approach: 1]. EMBRACING UNCERTAINTY AND POSSIBILITY In quantum mechanics, particles exist in multiple states simultaneously until observed. Similarly, strategic leaders must embrace uncertainty and consider multiple possibilities. Instead of rigid, deterministic planning, we should: - Envision multiple potential outcomes for any situation - Explore diverse approaches with input from various stakeholders - Maintain flexibility to pivot as circumstances evolve This "superposition" mindset allows us to thrive on uncertainty and foster innovation at the "edge of chaos". 2]. THE POWER OF OBSERVATION AND INTENTION Just as observing quantum particles affects their state, a leader's focus shapes organizational reality. We must be mindful of our "observer effect" by: - Cultivating awareness of our perceptual biases - Intentionally creating a positive organizational culture - Balancing focus between efficiency (exploiting) and effectiveness (exploring) Our attention and expectations have ripple effects throughout the organization. 3]. INTERCONNECTEDNESS AND EMERGENCE Quantum entanglement demonstrates the interconnected nature of particles. In leadership, this translates to: - Fostering strong relationships and networks within teams - Recognizing that small actions can have far-reaching impacts - Allowing for bottom-up, self-organizing structures to emerge By cultivating a high "connectivity quotient," we can create teams that perform beyond the sum of their parts. 4]. ADAPTING TO COMPLEXITY Quantum uncertainty challenges traditional, linear planning. To lead effectively in complex systems: - Adopt an adaptive, learning-oriented approach to strategy - Encourage experimentation and "quantum tunneling" to overcome barriers - Focus on creating conditions for innovation rather than rigid objectives. By embracing these quantum principles, we can develop a more nuanced, flexible, and effective approach to strategic leadership in our rapidly changing world.

Quantum algorithms for algebraic problems  https://lnkd.in/e3-xdAUC Quantum computers can execute algorithms that dramatically outperform classical computation. As the best-known example, Shor discovered an efficient quantum algorithm for factoring integers, whereas factoring appears to be difficult for classical computers. Understanding what other computational problems can be solved significantly faster using quantum algorithms is one of the major challenges in the theory of quantum computation, and such algorithms motivate the formidable task of building a large-scale quantum computer. This article reviews the current state of quantum algorithms, focusing on algorithms with superpolynomial speedup over classical computation, and in particular, on problems with an algebraic flavor. 

Scientists from Russia and China have allegedly achieved quantum communication encryption using secure keys transmitted by China's quantum satellite Mozi. Quantum communication encryption uses the principles of quantum mechanics to establish secure communication channels. It aims to create unbreakable encryption, making it highly attractive for applications where the highest level of security is essential, such as in transmitting sensitive information in fields like finance, government, and defense. This breakthrough demonstrates the technical feasibility of establishing a BRICS (Brazil, Russia, India, China, South Africa) quantum communication network. The researchers managed to cover a distance of 3,800 kilometers between a ground station near Moscow and another close to Urumqi in China's Xinjiang region, transmitting two encoded images secured by quantum keys, reported the South China Morning Post. The first full-cycle quantum communication test between the two countries took place in March 2022, according to Alexey Fedorov from Russia’s National University of Science and Technology and the Russian Quantum Centre. A secret key was passed on during this experiment, transferring two coded messages decrypted using keys based on a quote from Chinese philosopher Mozi and an equation from Soviet physicist Lev Landau. The collaboration utilized China’s quantum satellite, Mozi, which has paved the way for the development of both national and international quantum communication networks. Quantum communication provides a secure way to transfer information, making it resistant to eavesdropping by hackers. The encrypted data is transferred as ones and zeros along with a quantum key, ensuring that unauthorized individuals cannot access the information. However, limitations in ground-based quantum key distribution arise due to the loss of photons over long distances, capping optical fiber cable transfers at around 1,000 kilometers. China’s Mozi, the world's first quantum communication satellite launched in 2016, overcomes this. It allows for long-distance quantum transmission. The satellite enables the establishment of a national quantum network in China, spanning thousands of kilometers.

Diamonds as the next-generation data storage? Scientists have discovered how to manipulate quantum defects at the atomic level to store data in diamonds. Here's how it works: In a regular diamond, carbon atoms form a perfect crystal structure. But scientists can deliberately create tiny imperfections by removing a carbon atom and replacing it with a nitrogen atom. This creates what's called a Nitrogen-Vacancy center. These NV centers are quantum physical systems that can store information using the spin states of electrons - like tiny hard drives that work at the atomic scale. But here's what makes this technology incredible: Unlike most quantum systems that need temperatures near absolute zero, these diamond quantum memories work at room temperature. They can maintain quantum information for hours, even days - which is extraordinary in the quantum world. Right now, research teams at MIT, Harvard, and Delft University are racing to develop this technology. While we're still years away from diamond-based data storage in our devices, the potential is massive - imagine quantum computers and ultra-secure communication networks, all powered by these engineered diamonds. #tech #futuretech #stem

A research team at TU Wien has uncovered something astonishing: quantum entanglement the mysterious bond connecting particles across space doesn’t form instantly. Instead, it takes about 232 attoseconds (a quintillionth of a second) to fully emerge. Using advanced computer simulations of atoms hit by laser pulses, scientists observed that entanglement develops gradually as one electron escapes and another shifts energy levels, slowly weaving their quantum link through time. This finding challenges decades of assumptions that entanglement happens outside of time itself. It reveals that even the universe’s fastest phenomena have measurable stages a kind of “quantum heartbeat.” Researchers now aim to confirm the results experimentally, a daunting task at speeds where light barely crosses a human hair’s width. Cracking these fleeting moments could reshape quantum computing, encryption, and communication, showing that even instant mysteries unfold with rhythm and order. #RMScienceTechInvest #NASA https://lnkd.in/dgWFAvWr https://lnkd.in/dvvUF3sb
