Amaravati hits major milestone in quantum computing, dilution refrigerator reaches 4 Kelvin Andhra Pradesh's quantum computing facility in Amaravati has achieved a major milestone with its indigenous dilution refrigerator as it reached 4 Kelvin (minus 269 degrees Celcius). Here is what this means for the future of quantum computing in India. Technology is progressing fast. Today, we hear discussions about how AI and AI agents are changing the way the world works. But there is another technology that is gaining traction globally, quantum computing. With Andhra Pradesh’s Amaravati Quantum Valley (AQV) aiming to lead this field. And now, Amaravati has reached a major milestone with its indigenous dilution refrigerator reaching 4 Kelvin, or minus 269 degrees Celsius. The indigenous dilution refrigerator was created at the Quantum Reference Facility in Medha Towers, Amaravati. The Andhra Pradesh government said this was the first major technical milestone for the state’s quantum hardware facility. According to reports, the system was built with more than 80 per cent domestically-sourced components, making it one of the coldest temperatures achieved in a research facility in India with such a high level of local materials. What is quantum computing? Before we delve into why this matters, we need to understand quantum computing. You see, quantum computing is more complex than regular computers. Unlike regular computers that store information in bits – 0 or 1 – quantum computers use qubits. In simple terms, qubits allow us to find out different probabilities and answers all at once, instead of going through each problem individually. This, in theory, can allow us to do research or solve problems that could've taken hundreds of years in days. But qubits are far more fragile, and need precise conditions to function. They must be cooled to near absolute zero – around 15 millikelvin, colder than
