SUMMARY:Connecting the dots: the interactions and environment of elect
 rons in zero dimensions\, R. G. Herb Condensed Matter Seminar\, Xanthe
  Croot\, University of Sydney
DESCRIPTION:Quantum information can be encoded in the spin and charge 
 states of electrons in semiconductor quantum dots. While qubits in the
 se zero-dimensional systems have exhibited long coherence times and ex
 cellent one and two-qubit operability\, there remain challenges - name
 ly\, unwanted environmental coupling and issues of scalability. In thi
 s talk\, I will discuss interactions between microwave-driven electron
 s in GaAs quantum dots and their phonon environment\, which can lead t
 o qubit population inversions and decoherence. Techniques for probing 
 the charge environment of the qubit will also be explored\, and I will
  briefly touch on scalable readout protocols. Finally\, I will outline
  progress in an architecture designed to facilitate controllable coupl
 ing between separated qubits\, an important outstanding challenge for 
 the field.
