What’s a Quantum Repeater and Why Do We Need It? Quantum repeaters are devices designed to extend the range of quantum communication over long distances. Unlike classical repeaters that simply amplify a signal, quantum repeaters overcome signal loss by using Quantum Entanglement and a process called Entanglement Swapping to create a long-distance entangled connection. How

Now that information is converted into qubits, how are qubits sent from one quantum node to another in a Quantum Network? Qubits aren’t sent directly like classical bits in a quantum network. Instead, the process relies on a key principle of quantum mechanics called quantum entanglement and a protocol called quantum teleportation. The Qubit Journey

In a world increasingly shaped by quantum technologies, one question often puzzles even seasoned technologists: Why can’t analogue information be directly converted into qubits? At first glance, it seems intuitive—after all, quantum systems are inherently physical and continuous. But the reality is more nuanced. Analogue information isn’t converted directly into qubits because the fundamental nature of quantum

In the last blog post, we touched the the concepts of bases and correlation in the context of QKD and kept it for a detailed explanation this week. Even before understanding bases and correlation, let’s take a step back and understand why these are discussed in the context of Quantum technology. Ever wondered how classical information represented as
