Quantum Computing Overview

• Quantum computers operate on quantum mechanics principles, dealing with the smallest particles in the universe.

• Key principles include superposition and entanglement, allowing qubits to hold two units of information simultaneously.

• Challenges in building quantum computers include high costs, maintaining qubit stability, and the need for large-scale qubits.

• Key milestones include Shor’s algorithm, IBM’s Q System One, Google’s ‘Sycamore’ processor, and Google’s quantum chip, Willow.

• Building quantum computers remains costly and complex, with maintaining many qubits stable challenging due to error rates and decoherence.

• India launched the National Quantum Mission in 2023 to develop quantum computers.
