Abstract

As a promising physical realization of a quantum computer, we discuss a system with stacked quantum dots buried in adjacent to the channel of a spin field-effect transistor. In this scheme, one can measure only the edge qubit (nearest to the channel) via the spin-blockade measurement, but still it is possible to know the state of the whole qubits.
