IIT-Mandi Developing Quantum Computer Working at Room Temperature using Photons For Computing

Technology News ,India :-  The Indian Institute of Technology, Mandi, is making groundbreaking strides in quantum computing by developing a first-of-its-kind indigenous room-temperature quantum computer that utilizes photons for high-speed calculations, as revealed by officials.

Part of the National Quantum Mission, this unique computer possesses the ability to analyze data and propose solutions with an impressive 86% accuracy, all without the reliance on traditional algorithms. Quantum computing, an emerging technology, leverages the principles of quantum mechanics to solve complex problems beyond the capabilities of classical computers.

Chairperson of the Center for Quantum Science and Technologies (CQST) at IIT-Mandi, C S Yadav, stated, “We are constructing a room-temperature optical quantum computer capable of solving feature learning and classification problems instantly. With a sophisticated user interface, quantum simulator, and processing capabilities, our computer will function as a graphics processor (GPU), seamlessly handling inputs like videos or photographs.”

The quantum computer will extract models to elucidate hidden dynamics within input data and provide output as a quantum live feed. Yadav highlighted the unique approach, stating, “Composing a quantum algorithm is tedious. Yet our computer will mirror the inquisitive mind of a scientist, swiftly suggesting an approximate theoretical model for unknown big data with an 86% accuracy, all without relying on algorithms.”

While acknowledging other players like Google and IBM in the quantum computing field, Yadav emphasized their objective to develop a photon-based quantum computer at room temperature, in contrast to the superconducting Josephson junction qubit-based systems that require extremely low temperatures.

Explaining the technology, Yadav stated that the room-temperature optical quantum computer would use light for fast calculations, employing quantum bits (qubits) to exist in multiple states simultaneously for rapid processing. The system is designed to update itself and erase memory using a special gel.

The team at IIT-Mandi is focused on scaling up the quantum computing system from handling 16 tasks to 1,024 tasks simultaneously. Key components, including a single photon source, a phase-sensitive single-photon avalanche diode, and a multipurpose coincidence counter, are being developed to high levels of reliability and effectiveness.

IIT-Mandi Director Laxmidhar Behera expressed optimism about the impact of the Center for Quantum Science and Technologies, stating, “Through the National Quantum Mission, we are advancing the field with groundbreaking innovations aimed at enhancing feature learning and classification capabilities across genetics, astrophysics, finance, and weather forecasting. By collaborating with startups and establishing a robust supply chain, we aim to commercialize these components locally, fostering indigenous innovation and aligning with the aspirations of the National Quantum Mission.”
