  2. Measurable Performance Objectives • Students will understand the difference between classic and quantum mechanics • Students will acquire basic understanding of quantum mechanics • Students will demonstrate the knowledge of spintronics • Students will be able to define qubit • Students will be able to compare conventional microelectronic and spintronic devices • Students will gain an insight into future technology • Students will be able to design a top of the technology computer.

  3. Opening discussionComputer Technology….. then and now • Storage devices • Hard drive storage capacity • RAMs • Speed • Limiting factors

  4. Materials • Internet access • Paper and pencil

  5. Concepts, Principles, and Facts • Classic vs. quantum mechanics • Introduction to quantum mechanics • Spin-based electronics or spintronics • Qubit • Conventional microelectronic vs. spintronic devices • Future technology • Available commercial products.

  6. Classic vs. quantum mechanics • Macro world vs. the nano world • What is quantum mechanics? • Why do we need quantum mechanics? • Measurements in the macro vs nano world

  7. Quantum Mechanicsoffers explanation for • Discrete energy levels • The theory of wave-particle dual nature • Quantum tunneling • The Heisenberg uncertainty principle • Spin of a particle

  8. Spintronics • Spin-based electronics • Charge-based electronics vs. spin-based electronics • Advantages of spin-based electronics • Spintronics storage devices

  9. Define qubit • Bit vs. qubit • Representation of a qubit with bra-ket notation, |o>, |1> and superposition of the two
