Quantum computing is a form of computation that relies on quantum-mechanical principles such as superposition and entanglement. Unlike classical bits that represent either 0 or 1, quantum bits (qubits) can exist in multiple states simultaneously. This enables potentially massive speedups for specific problems like molecular simulation, complex optimization, and cryptography. However, qubits are extremely fragile, require near-absolute-zero operating conditions, suffer from high error rates, and current systems are limited to small, noisy devices in the NISQ (Noisy Intermediate-Scale Quantum) era.
