"Bengaluru deep-tech firm launches India's first quantum processor foundry"
Qubit
quantum bit; fundamental unit exploiting superposition and entanglement for quantum computation.
Superconducting qubit
qubit implemented using superconducting circuits cooled near absolute zero.
India's pursuit of quantum technology sovereignty sits within a broader historical pattern of ambitious technology vision followed by incomplete commercialisation. From the Semiconductor Complex Limited (SCL) established in the 1970s to the Electronics Corporation of India Limited (ECIL) founded in 1967, India demonstrated early intent to build indigenous hardware capabilities — but these efforts remained largely confined to public-sector enclaves, insulated from market competition and global supply chains. The liberalisation of 1991 partially corrected structural distortions, yet India's technology economy remained services-led rather than product- or platform-led for decades.
The current policy framework attempts a structural correction through mission-mode programmes. The National Quantum Mission (NQM), approved in 2023 with an outlay of approximately ₹6,003 crore over eight years, is the nodal initiative under the Department of Science and Technology (DST). Its mandate spans quantum computing, quantum communication, quantum sensing, and quantum materials. Critically, the NQM targets developing intermediate-scale quantum computers with 50–1,000 physical qubits and envisages setting up four Thematic Hubs (T-Hubs) in academic and national R&D institutes to anchor the ecosystem. This mission-mode approach mirrors the logic of the India Semiconductor Mission (ISM) under MeitY, which carries an outlay of approximately ₹76,000 crore and uses a production-linked incentive architecture to attract fabrication investment.
A qubit (quantum bit) is the fundamental unit of quantum information, exploiting quantum mechanical properties — superposition and entanglement — to perform computations that classical binary bits cannot efficiently execute. Unlike a classical bit that is either 0 or 1, a qubit can exist in both states simultaneously, enabling quantum computers to process exponentially larger solution spaces for specific problem classes: cryptography, drug discovery, materials simulation, logistics optimisation, and financial modelling.
Two dominant qubit architectures are relevant here. Transmon-based superconducting qubits are the most commercially mature approach, used by leading global players and now by India's own fabricated processors — the 8-qubit Qvidya, 25-qubit Indus, and 64-qubit Kaveri. Fluxonium qubits, used in the 9-qubit Yukti, represent a newer design with potentially superior coherence times and error-correction properties. …
