Rajeev Chandrasekhar, Minister of State for Electronics & Information Technology, launched QSim – Quantum Computer Simulator Toolkit, to enable Researchers and Students to carryout research in Quantum Computing in a cost effective manner.


  • QSim is an outcome of the project “Design and Development of Quantum Computer Toolkit (Simulator, Workbench) and Capacity Building”.

  • This is one of the first initiatives in the country to address the common challenge of advancing the Quantum Computing research frontiers in India.

  • 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 - Feature Highlights

  • Intuitive UI: QSim offers a robust 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.

QSim - Offering Models

  • PARAM SHAVAK QSim - Standalone system with Quantum Simulator in a box

  • PARAM QSim Cloud - Available on cloud using HPC infrastructure PARAM SIDDHI AI (developed and deployed under NSM program)
