Storage Qubits and Their Potential Implementation Through a Semiconductor Double Quantum Dot

Abstract

In the context of a semiconductor based implementation of a quantum computer the idea of a quantum storage bit is presented and a possible implementation using a double quantum dot structure is considered. A measurement scheme using a stimulated Raman adiabatic passage is discussed.
