Hello everybody. I'd like you all to imagine a scenario where you're sitting in front of your desk one very nice Monday morning and with a nice cup of coffee and the morning light glinting through the window. You open up your laptop and you fire up Gmail and one of the emails catches your eye.one titled college application results and there you are just a mouse's click away from transporting yourself to a reality where you get accepted or devastatingly rejected and sent back to square one. Well, let's take ...

Online Fraud Threat - Online frauds are a growing threat, costing over $300,000 every second globally [1] - Position-based cryptography can prevent countless scams by ensuring website authenticity [3] - Secure position verification can also secure areas beyond online fraud, such as wartime situations [4] Quantum Technology Solution - Classical information can be copied, making secure position verification challenging [6][7] - Quantum information, using qubits, cannot be perfectly copied due to the no-cloning theorem [8] - Quantum position verification requires secure communication via entanglement-based quantum communication networks and position-based authentication using light speed communication [9][10] Quantum Entanglement - Quantum entanglement links particles, influencing them instantly regardless of distance [11] - Entanglement-based quantum security is unhackable, even with quantum computers [16] - Entanglement ensures privacy, as any attempt to steal information disrupts the quantum state [15] Quantum Networks and Quantum Internet - Multi-node quantum networks connect verifiers and provers, enabling secure information transmission [16] - Quantum networks offer unprecedented security and powerful computation for sectors like banking, finance, defense, telecommunication, and healthcare [17] - Quantum internet complements the classical internet, offering ultra-secure communication and distributed quantum computing [18] Quantum Network Development - Practical quantum networks are being developed globally, including in India [20] - Research groups have developed entanglement-based hybrid multi-node quantum networks spanning hundreds of kilometers [20] - The goal is to integrate quantum networks with existing classical networks, leading to a future unhackable quantum internet [22]
