Quantum computing is an exciting and complex field that aims to revolutionise how we process information. To understand it in simple terms, let’s start with classical computing.

In classical computers, we use bits to store and process information. A bit can be either a 0 or a 1, representing two possible states. These bits are like tiny switches that can be turned on or off.

Quantum computing, on the other hand, uses quantum bits, or qubits, which are a bit like magical switches. Unlike classical bits, qubits can exist in multiple states simultaneously. This is due to a fundamental principle in quantum physics called superposition.

Imagine a qubit as a spinning coin. In classical computing, the coin can be either heads or tails, representing a 0 or a 1. In quantum computing, the coin can be in a superposition of both states at the same time, like spinning on its edge. This superposition allows qubits to hold and process much more information in parallel.

Another remarkable property of qubits is entanglement. When qubits become entangled, the state of one qubit becomes intimately linked to the state of another qubit, no matter how far apart they are. Changing the state of one qubit instantly affects the state of the other, even if they are light-years away. This property enables quantum computers to perform certain calculations much faster than classical computers.

By harnessing superposition and entanglement, quantum computers can perform complex calculations and solve problems that are practically impossible or extremely time-consuming for classical computers. They have the potential to revolutionise fields like cryptography, drug discovery, optimisation, and simulation, opening doors to new discoveries and advancements.

However, it’s worth noting that quantum computing is still in its early stages, and building practical, error-resistant quantum computers is a significant scientific and engineering challenge. But scientists and researchers are making remarkable progress, and the future of quantum computing holds great promise.

The timeline and rollout of computers happened a little something like below:
