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.

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

Quantum Mechanics offers explanation for Discrete energy levels The theory of wave-particle dual nature Quantum tunneling The Heisenberg uncertainty principle Spin of a particle

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

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