  1. Future Computing Post silicon computing

  2. Silicon • Reaching limits of ability to work with silicon…

  3. 3D Gates • Trick 1:Fancier ways of buildingwith silicon

  4. 3D Gates • Trick 2:New materials

  5. Molecular Computation • Trick 3: Molecular computation • DNA Storage: 700 terabytes in one gram

  6. DNA Computing • Structure computational problemsas molecular structures • Find answer chemically

  7. Quantum Mechanics • Trick 4: Quantum Mechanics • Rules that govern sub atomic physics • Particles can teleport • Particles can be entangled and read each other's "minds" across the universe • Everything is random until it is observed…then it changes to match observation

  8. And • Switches can be both on and off with some probability…

  9. Video • How does a Quantum Computer Work?

  10. Scaling

  11. 100 • A problem space is represented by 100 bits2100 possible answers • Conventional computer: • 1,000,000,000 solutions checked per second • 40 trillion years to solve

  12. 100 • A problem space is represented by 100 bits2100 possible answers • Quantum computer with 100 bits • Try all states at once • Seconds (+ lots of setup time) • Answer is only probably correct – need multiple runs to confirm…

  13. Reality • Solving 3 x 5 = 15 the hard way

  14. Reality • Special purpose record: • ~16 bits • Factor 143 with 50% accuracy
