Outline of Final Research Achievements |
Electron spins are possible candidates as qubits for solid state quantum computer. The most promising approach for spin control is based on electron spin resonance (ESR). However, ESR requires external magnetic fields, which are generated in spaces that greatly exceed individual electrons, thus making these complex and inefficient techniques unsuitable for device applications. We carried out spin transport experiments using trajectly-controlled "dynamic dots", which are realized by applying surface acoustic waves on semiconductor quantum wells. We observed the spin behavior of ESR even in the absence of external magnetic fields. This phenomenon allows us to manipulate spins in any three-dimensional direction by designing appropriate channel structures.
