Indian Quantum Algorithm Achievement in Quantum Computing

Context: Indian Quantum Algorithm Achievement

Scientists from BITS Pilani, working with IBM Quantum, have developed a quantum algorithm that successfully simulated subatomic particle behaviour on a 120-qubit IBM quantum processor.

This is the first Indian achievement to be recognised as an active quantum advantage by the Quantum Advantage Tracker.

Quantum Advantage: Basics

What is Quantum Advantage?

Quantum advantage is achieved when a quantum computer solves a practical problem faster or better than the best classical computer.

Why is it important?

It demonstrates the real-world usefulness of quantum computing beyond theory.

It shows that quantum computers can solve problems that are extremely difficult for classical computers.

How does it work?

Classical computers use bits, which represent either 0 or 1.

Quantum computers use qubits, which can process multiple states simultaneously.

This gives quantum computers the ability to perform certain complex calculations more efficiently.
