About this deck
Classical bits are switches: 0 or 1, definite at every instant. A qubit is a quantum object whose state is a continuous combination — a superposition — of 0 and 1, collapsing only when measured. Key sections include: QUANTUM COMPUTING A different kind of computer.; A bit holds one answer. A qubit holds both.; Superposition. Entanglement.; The Bloch sphere; Feynman, 1982; Shor's algorithm breaks RSA; Grover: √N search; Four serious hardware bets; Qubits are delicate; Logical qubits, demonstrated.
