What Is Quantum Computing (Quick Refresher)
Quantum computing represents a fundamentally new approach to computation compared with classical computers. Instead of relying on binary bits (0 or 1), quantum systems leverage quantum superposition, entanglement, and interference to process information in ways that classical machines cannot.
- Quantum superposition allows qubits to exist in multiple states simultaneously, vastly increasing computational parallelism.
- Quantum entanglement links qubits such that the state of one instantly influences another, enabling faster, correlated computations.
- Quantum interference helps in amplifying correct solutions while canceling out wrong ones in quantum algorithms.
| Feature | Classical Computers | Quantum Computers |
| Basic unit | Bit (0 or 1) | Qubit (0, 1, or superposition) |
| Parallelism | Sequential or multi-threaded | Massive parallelism via superposition |
| Error sensitivity | Low | High, needs quantum error correction |
| Applications | General computing | Optimization, molecular simulation, AI, cryptography |
Quantum computing is not about replacing classical machines but complementing them, particularly for problems like portfolio optimization, material simulations, and drug discovery quantum computing, where classical approaches hit limitations.
