Scientists from the Defence Research and Development Organisation’s Young Scientists Laboratory for Quantum Technologies (DYSL-QT), Pune, in collaboration with the Tata Institute of Fundamental Research (TIFR), Mumbai, have completed end-to-end testing of a 6-qubit quantum processor.
This cutting-edge technology is based on superconducting circuit technology and marks a pivotal milestone in India’s burgeoning quantum research sector.
The demonstration at TIFR Mumbai’s Colaba campus showcased the seamless execution of a quantum circuit submitted via a cloud-based interface developed by Tata Consultancy Services (TCS). The process involved submitting the quantum circuit, executing it on the quantum hardware, and updating the cloud interface with the computed results. This achievement underscores India’s growing proficiency in quantum computing, which promises to revolutionize the cryptography and material science industries.
Based on a novel ring-resonator design invented at TIFR, the quantum processor's architecture results from a robust three-way collaboration between DYSL-QT, TIFR, and TCS. The qubits, the fundamental units of quantum information, were meticulously designed and fabricated at TIFR. Meanwhile, the control and measurement apparatus was developed by DYSL-QT scientists, who combined commercial off-the-shelf electronics with custom-programmed development boards, highlighting the innovative approach of leveraging existing technology while pushing the boundaries of quantum research.
As the project progresses, the team focuses on optimizing the system's performance, planning to make the quantum processor more widely accessible for educational purposes and research and as a test bed for superconducting quantum devices. This is part of a broader vision to scale up the number of qubits and assess the scalability of the technology, a critical step in the global race toward practical and commercially viable quantum computers.
The next development phase will address the complex scaling challenges, including the technological hurdles time and financial resources required. The project aims to adopt a holistic approach, integrating quantum theory with engineering solutions and assessing business feasibility. This initiative positions India as a critical player in the rapidly evolving landscape of quantum computing, with the potential to influence a wide range of sectors soon.
As quantum technology edges closer to practical applications, this collaboration sets the stage for further breakthroughs, reinforcing India’s role in the global quantum race.
