Understanding Quantum Computing
1. What is Quantum Computing?
Quantum computing leverages the principles of quantum mechanics to perform computations in ways that classical computers cannot. Unlike classical bits, which represent either a 0 or a 1, quantum bits (qubits) can represent multiple states simultaneously due to the principles of superposition and entanglement. This allows quantum computers to process a vast amount of data in parallel, potentially solving complex problems more efficiently.
