DRDO’s Junior Researchers Complete Extensive Testing of 6-Qubit Quantum Processor with Superconducting Technology
Scientists from the DRDO Young Scientists Laboratory for Quantum Technologies (DYSL-QT) in Pune and the Tata Institute of Fundamental Research (TIFR) in Mumbai have achieved a significant milestone in quantum computing. They’ve completed end-to-end testing of a cutting-edge 6-qubit quantum processor using superconducting circuit technology. This groundbreaking demonstration was presented to the apex committee overseeing DYSL-QT and involved the seamless integration of a cloud-based quantum circuit submission, execution on quantum hardware, and real-time updates to the cloud interface with the results.
This ambitious project, based at TIFR’s Colaba campus in Mumbai, represents a collaborative effort between DYSL-QT, TIFR, and Tata Consultancy Services (TCS). The DYSL-QT team engineered the control and measurement systems using a mix of commercial electronics and custom development boards. Meanwhile, TIFR designed and fabricated the qubits, leveraging a novel ring-resonator architecture. TCS developed the cloud-based interface that connects to the quantum hardware.
Currently, the team is focused on fine-tuning system performance before making it available for broader use. The goal is to provide access for educational purposes, research, and as a testing ground for superconducting quantum devices. Future efforts will center on scaling up the number of qubits and addressing challenges related to technology, development effort, and commercialization. This includes a comprehensive evaluation from theoretical foundations to practical engineering and business viability.
