TEDx Talks· 2026-03-05 16:42
हेलो एवरीवन। हमारा दिमाग, हमारी इंट्यूशन हमें तो बस हजारों फैसले लेने में मदद करती है। बट आज यहां पे मैं एक छोटी सी स्टोरी सुनाने आया हूं। बस एक छोटा सा डिसीजन लेना आप। एक ऐसी सिचुएशन जिसमें यही इंट्यूशन शायद हमारी सबसे बड़ी दुश्मन बन जाने वाली है। इमेजिन करो एक ऐसी जानलेवा बीमारी फैल रही है जिसको सॉल्व करने के लिए जिसका इलाज ढूंढने के लिए हमने बहुत पावरफुल सुपर कंप्यूटर में प्रोग्राम को रन किया है। चल रहा है धीरे-धीरे। हमारे पास दो ऑप्शन एक बहुत बड़ा डिसीजन लेना आप। पहला ऑप्शन है कि हम प्रोग्राम को आज ही र ...

Quantum Computing Overview - The field is at the edge of technology, with potential advancements in medicine, technology, and materials science if fundamental problems in complex molecule understanding and optimization are solved [1][2][3] - Quantum computers are being developed to address problems currently intractable for even the fastest supercomputers, particularly in areas like energy optimization and city traffic management involving billions of variables [2][3][4] - Quantum computers leverage the principles of quantum mechanics, specifically superposition and entanglement, to potentially achieve faster algorithms [5][8] Quantum Principles - Qubits, the fundamental unit of quantum computers, can exist in a superposition of 0 and 1 simultaneously, unlike classical bits which are either 0 or 1 [10][11] - Entanglement creates an instantaneous connection between two particles, regardless of distance, allowing for correlated quantum state collapses [8][14][15] - Quantum entanglement, though difficult to generate, is a valuable resource with potential applications in quantum teleportation, which involves transferring quantum information [16][17][18] Applications and Future Directions - Quantum computing has potential applications in medicine, artificial intelligence, energy-efficient battery development, and cybersecurity [19] - Quantum computers could pose a threat to current cybersecurity systems, necessitating the development of quantum-resistant security measures [20] - Current quantum computers are still in early stages, being small, noisy prototypes with significant technological and theoretical challenges to overcome [22] - The field is focused on developing algorithms for error correction and future applications on fault-tolerant quantum computers [22][23] - Quantum computers are not a panacea but rather specialized machines for solving well-structured, crucial problems, particularly in understanding physics and the universe [24][25]

Quantum Computing Fundamentals - Quantum physics helps create many different elements that shape our reality, such as lasers, clocks, and microchips [10] - Quantum states are fragile and require extremely low temperatures and isolation to operate, necessitating specialized labs [26][27][28] - Qubits, unlike classical bits, can exist in a superposition of states, enabling probabilistic counting and increased computational complexity [23][24] Quantum Computing Applications & Potential - Quantum computers can perform complex calculations simultaneously, potentially breaking current data encryption methods [35][36] - Quantum computing has potential applications in complex analysis, quantum sensing for material behavior, drug development, and solving complex graph problems [36][37][38][39] - Quantum computers could revolutionize optimization problems, potentially reducing computation time from days or years to minutes [39] Quantum Computing Infrastructure & Technology - IBM's quantum computing system requires a complex cooling infrastructure using helium-3 and helium-4 to achieve temperatures of 20 millikelvins, colder than the vacuum of space (-273°C) [29][30][31][32] - The core computing unit in quantum systems is a small component within a larger infrastructure designed for measurement and cooling [31] Quantum Entanglement - Quantum entanglement allows for the creation of quantum states in one location and their transfer to another, potentially enabling quantum coding [20] - Entanglement demonstrates that measuring the state of one entangled particle instantly determines the state of the other, without information transfer [19][20]
