  1. Quantum Computing Physics 496 Jeffrey Kiyabu

  2. Quantum Computing • Bits & Qubits • Quantum phenomena A. Superposition B. Parallelism C. Interference • Computation A. Unitary operators (logic gates) B. Algorithms • Technological/Systematic Obstacles A. Decoherence B. Hardware architecture

  3. Bits & Qubits Bit – 0 or 1 Qubit – quantum mechanical two-state system (spin up, spin down or 0, 1); a system of n qubits represents 2n possible states

  4. Quantum Phenomena • Superposition • Parallelism • Interference

  5. Computation • Unitary operators (logic gates) e.g. not-gate • Algorithm – sequence of logic gates operating on a system e.g. quantum search algorithm

  6. Obstacles • Decoherence – information in the system lost to environment • Hardware architecture

  7. Quantum Computing • Bits & Qubits • Quantum phenomena A. Superposition B. Interference C. Parallelism • Computation A. Unitary operators (logic gates) B. Algorithms • Technological/Systematic Obstacles A. Decoherence B. Hardware architecture

  8. “Where a calculator on the Eniac is equipped with 18000 vacuum tubes and weighs 30 tons, computers in the future may have only 1000 tubes and weigh only 1 1/2 tons," -Popular Mechanics, March 1949.
