Bob (Quantum Computing)

Bob, in quantum computing, is a hypothetical participant often used to illustrate quantum principles. He operates a quantum computer that leverages qubits—quantum bits—which can exist in multiple states simultaneously thanks to superposition. Unlike classical bits, qubits enable Bob to perform complex calculations more efficiently for specific problems. Quantum entanglement, another key concept, links qubits such that the state of one instantly influences the others, regardless of distance. These properties allow Bob's quantum computer to potentially solve certain problems much faster than traditional computers, opening new possibilities in fields like cryptography, optimization, and simulation.
