Spins for Quantum Information Processing

Abstract

Spintronics and Quantum Computation are both newly minted terms, and concepts, in physics. Depending on your point of view, they are almost exactly the same, or they are completely different. They both may be defined as a concept for using discrete, quantized degrees of freedom in a physical device to perform information-processing functions. But from this point of overlap, these two concepts are both more and less than the other. Spintronics concerns itself, of course, only with spins, spins in the solid state; quantum computing encompasses almost every possible quantum phenomenon in nature. But within its narrower setting, spintronics has a broader agenda, to facilitate and improve all possible forms of information processing using spin-based devices. Quantum computing actually has a narrower agenda: to devise and implement quantum-coherent strategies for computation and communication.
