Govt launches India's first Quantum Computer simulator toolkit for research

The Indian government launched country's first quantum computer simulator toolkit-QSim to aid cost effective research in quantum computing.  This project is being executed collaboratively by IISc Bangalore, IIT Roorkee and C-DAC with the support of Ministry of Electronics and Information Technology (MeitY), Government of India.

QSim allows researchers and students to write and debug Quantum Code that is essential for developing quantum algorithms. Quantum systems are highly sensitive to disturbances from environment, even necessary controls and observations perturb them. The available and upcoming Quantum devices are noisy and techniques to bring down the environmental error rate are being intensively pursued.

QSim allows researchers to explore Quantum Algorithms under idealized conditions and help prepare experiments to run on actual Quantum Hardware. QSim can serve as an important educational / research tool providing an excellent way to attract students / researchers to the field of Quantum Technology and provides a platform to acquire the skills of ‘programming’ as well as ‘designing’ real Quantum Hardware.

QSim feature highlights:

Intuitive UI: QSim offers a QC Simulator integrated with a GUI based Workbench allowing students / researchers to create Quantum programs, visualize the instant circuit generation and simulated outputs.

Simulate noisy Quantum logic circuits: Helps simulate Quantum circuits with and without noise and test how well various algorithms work with imperfect quantum components. This is essential to simulate real-life conditions.

Pre-loaded Quantum algorithms and examples: QSim comes loaded with Quantum programs and algorithms providing a head start to the users. E.g. QFT, Deutsch Jozsa, Grovers and so on.

Integrated with HPC: The quantum simulations are performed on powerful HPC resources allowing multiple users to submit jobs simultaneously with different QuBit configurations.

Addressing the event, Rajeev Chandrasekhar said that we are coming to an era where conventional computing power growth through the traditional means of silicon and semiconductor is drawing to a close and now we are going to see the next generation of computing power growth comes from a combination of software new architectures, system redesign and new system paradigms and that is where the quantum computing comes and is clearly going to be the cutting edge of the future demands of computing power. QSim is the Gateway for Indian scientists to take us in that direction.
