QSim

QSim (Quantum Computer Simulator Toolkit) is one of the initiatives of the Government of India to address the challenge of advancing Quantum Computing research in India. QSim enables researchers and students to do research in Quantum Computing. It allows for writing Quantum code, which is essential for developing quantum algorithms. It provides a platform to acquire skills in ‘programming’ and ‘designing’ real Quantum hardware. It helps to simulate quantum circuits with and without noise and test how well various algorithms work with imperfect quantum components. Quantum simulations are performed on powerful HPC resources allowing multiple users to submit jobs simultaneously with different qubit configurations. A standalone system with ‘Quantum Simulator in a box’ is available on PARAM SHAVAK (desktop Supercomputer), while PARAM QSim Cloud is available on HPC infrastructure (different PARAM series of Supercomputers).

Use Cases

• Provides Learning environment and platform for carrying out research in Quantum Computing

Salient Features

• Intuitive UI: QSim offers a robust QC Simulator integrated with a GUI based Workbench allowing students /researchers to create Quantum programs, and 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 is built around an indigenous density matrix simulator (designed by IISc Bangalore) based on the Qiskit framework.
