Quantum Computers vs Conventional Computers

Quantum computers differ from conventional computers in their method of calculation. Conventional computers use a deterministic paradigm, processing zeros and ones through electronic devices like transistors. Quantum computers, however, use a probabilistic scheme, making use of atoms and orbitals. They utilize principles of superposition and entanglement, which allow for simultaneous calculations and instant information transfer, respectively. Quantum computers can solve certain problems much faster than conventional computers, such as decomposing large numbers into prime numbers (Shor's algorithm) or solving systems of equations (HHL algorithm). They also have potential applications in anomaly detection and data classification.
