(IndiaTimes.com) India, which quickly scaled up to face the Y2K challenge, is now taking steps into quantum computing, although it doesn’t yet have a critical mass of people working in this field. The country has set up a programme, Quantum-Enabled Science and Technology (QuEST), where researchers from institutions such as the IISc, Indian Space Research Organisation and Tata Institute of Fundamental Research, have proposed to work on quantum computing and allied areas, including quantum safe cryptography and quantum communication. The Department of Science and Technology is funding research under QuEST, while some private players, such as QuNu Labs, are working on niche projects like using quantum key distribution to ensure encryption keys can be exchanged securely over networks.
“It (quantum safe encryption) depends on how sensitive or important your data is. If it needs to be secure for the next 50 or even 20/30 years, then you need to start working on it now,” said Sanjit Chatterjee, associate professor at the department of computer science and automation at IISc. “But if your data needs to be secure for shorter duration say, a year, or month, then you have time. It depends on your perspective.”
NOTE: This article has an extensive introduction into worldwide efforts in quantum tech development. India’s program is discussed in concluding paragraphs.
