An elongated quantum dot as a distributed charge sensor

Our latest paper demonstrates that we have upgraded charge sensors in silicon, which can now sense charges 500 nanometers apart from each other. This will help optimise the layouts of quantum processors.

This is a great demonstration of collaboration from team Quantum Motion (Sofia Patomäki, James Williams, Constance Lainé, Ross Leon, Michael Fogarty & others) with our partners imec and Niels Bohr Institute, University of Copenhagen.
