🔆 DILUTION REFRIGERATOR | QUANTUM TECHNOLOGY

📍 In News
🟢 DRDO has signed its first high-value deep-tech TDF agreement with Zero mK India Pvt. Ltd., Alwar, Rajasthan, to develop an indigenous 20 mK dilution refrigerator.

🔆 WHAT IS A DILUTION REFRIGERATOR?
🟢 A specialised cryogenic system capable of achieving extremely low temperatures in the millikelvin (mK) range, from just above absolute zero to 1 K.

📍 Working Mechanism
🟢 Uses a mixture of Helium-3 (³He) and Helium-4 (⁴He).
🟢 Below 0.87 K, the helium mixture separates into a concentrated phase and a dilute phase.
🟢 Helium-3 movement: When ³He moves from the concentrated phase into the dilute phase, more ³He moves across to replace it.
🟢 Cooling: This movement of ³He removes heat from the system, producing extremely low temperatures.

🔆 APPLICATIONS

📍 Quantum Technology
🟢 Enables the operation and testing of quantum computing platforms and associated quantum technologies.

📍 Strategic & Industrial Importance
🟢 Indigenous development can reduce dependence on imported cryogenic infrastructure.
🟢 Strengthens India’s domestic quantum technology ecosystem.

🔆 DRDO–ZERO mK INDIA PROJECT
🟢 Technology → Indigenous dilution refrigerator
🟢 Target temperature → 20 mK
🟢 Company → Zero mK India Pvt. Ltd.
🟢 Location → Alwar, Rajasthan
🟢 Scheme → Technology Development Fund (TDF)
🟢 Deep-tech corpus → ₹500 crore
🟢 Strategic alignment → National Quantum Mission

🔆 QUICK RECALL
Dilution Refrigerator → ³He + ⁴He → <0.87 K phase separation → Heat removal → Millikelvin temperatures → Quantum computing

📍 UPSC Mains Question
🟢 How can indigenous development of advanced cryogenic systems strengthen India’s capabilities in quantum technology and strategic technologies?
