Quantum dot and semiconductor research with the quantum physics group at NRC
Aviv PadawerBlatt1010Spin and hybrid spincharge qubits have been a longterm goal of the fields of Spintronics and Quantum Information. Such a qubit in an array would ideally interact separately from other qubits and “tunably” with a Microwave field. In this way, a single qubit may be turned “on”, interact with its environment to acquire information (for example, flip a spin state), and be turned “off” so it may indefinitely store that information. The necessary tunability for such a task has been demonstrated in a single hole of a ptype GaAs/AlGaAs Double Quantum Dot (DQD) with strong SpinOrbit Interaction (SOI), in which the interdot tunnel coupling is strong so that hybridized quantum molecular states form [1]. If the interdot coupling is reduced, this form of tunability is lost. However, a new phenomenon may permit tunability: the weak interdot coupling gives rise to distinct dotspecific quantum dot gfactors smoothly connected by the spinorbit interaction. By sweeping gate voltages such that we choose which dot is being probed, a qubit may be turned “on” or “off” as necessary. During my work terms with the lowtemperature Quantum Physics Group at the National Research Council of Canada, I investigated the appearance of dotspecific gfactors and partially characterized the double quantum dot system using a theoretical model.
