Query: Compressed Optimization of Device Architectures (CODA) for semiconductor
  quantum devices   Recent advances in nanotechnology have enabled researchers to manipulate
small collections of quantum mechanical objects with unprecedented accuracy. In
semiconductor quantum dot qubits, this manipulation requires controlling the
dot orbital energies, tunnel couplings, and the electron occupations. These
properties all depend on the voltages placed on the metallic electrodes that
define the device, whose positions are fixed once the device is fabricated.
While there has been much success with small numbers of dots, as the number of
dots grows, it will be increasingly useful to control these systems with as few
electrode voltage changes as possible. Here, we introduce a protocol, which we
call the Compressed Optimization of Device Architectures (CODA), in order to
both efficiently identify sparse sets of voltage changes that control quantum
systems, and to introduce a metric which can be used to compare device designs.
As an example of the former, we apply this method to simulated devices with up
to 100 quantum dots and show that CODA automatically tunes devices more
efficiently than other common nonlinear optimizers. To demonstrate the latter,
we determine the optimal lateral scale for a triple quantum dot, yielding a
simulated device that can be tuned with small voltage changes on a limited
number of electrodes.
