Understanding Quantum Computing

Quantum computing is fundamentally different from classical computing. Instead of using classical bits, which represent either a 0 or 1, quantum computers use qubits. Qubits can exist in multiple states simultaneously, thanks to the principles of superposition and entanglement. This property allows quantum computers to perform certain calculations exponentially faster than classical computers, making them exceptionally suited for specific tasks, such as solving complex optimization problems and simulating quantum systems.
