What is Quantum computing?

Quantum computing is a new way of computing that uses the principles of quantum mechanics to perform calculations. In traditional computing, data is processed using bits, which are either a 0 or a 1. But in quantum computing, the data is processed using quantum bits or qubits, which can be both a 0 and a 1 at the same time. This property of qubits is called superposition, which allows for multiple calculations to be performed simultaneously, making quantum computing exponentially faster than traditional computing for certain types of problems.

Foundational Concepts of Quantum Mechanics
