| Research Abstract |
We developed a flying charge qubit device on semiconductor, which is suitable for generation of non-local entanglement and qubit multiplication. We also developed a technology to transfer a single electron between distant quantum dots through a depleted 1D wire. Combining these technologies should allow for creation of a non-local entangled state in a single electron unit, which is essential for quantum computation. We also aimed for splitting Cooper pairs in superconductor-normal metal junctions. For preparation, we investigated and revealed basic electronic properties of graphene used as a normal metal.
