Part 3/9:
The Core Principles of Quantum Computers
At the heart of a quantum computer is quantum coherence, which allows multiple quantum bits (qubits) to operate together cohesively through entanglement. Riddle explores this with examples like superatoms and superconductors, showing how cooling atoms can achieve coherence to form a unified quantum system. This property enables quantum computers to handle complex problems through superposition, allowing simultaneous calculations that lead to exponentially greater processing power compared to classical digital computers.
