The field of semiconductor electronics has brought up a revolution in the field of quantum computers. Present semiconductor technology can be easily integrated with the spintronic technology to provide much needed quantum computing devices.
The word spintonics is collection of two words: Spin and Electronics.
Conventional electronics uses charge of electrons to present and transmit information. For example if +5V represent state "1" and 0.5 V represent state "0" then we still need about 10^18 electrons to represent state 1 and almost nearly 10^17 electrons to represent state 2.
In spintronic devices, instead of charge, the intrinsic property called "spin" is used to represent and transfer information. Electron has a spin of +1/2 and -1/2 each of which can represent state "0" and "1" independently. The main advantage is that here individual electrons represent a state and hence processing becomes superfast and consumes very less energy.
Challenges in present technology for spintronics is that individual spins should be controlled precisely during representation and transfer of information. This can be acheived at very low temperatures in some material but not at room temeparatures which is the actual practical range of operation.
Spins can be read electrically, magneticlaly and optically and hence these provides spintonics with different classification of sintronic materials required. Further discussions will be given henceforth as this blog grows.
Questions and comments are welcome.
