Abstract

A method is provided for operating a fractional quantum Hall apparatus including a set of interferometers, each having a cell and a set of gate electrodes located around the cell. The method includes calibrating each one of the interferometers to confine a droplet of a 2D charge carrier gas in a fractional quantum Hall effect state of filling factor 17/5 or 12/5, while a reentrant phase of integer quantum Hall effect states of the 2D charge carrier gas is located between the area of the droplet in a fractional quantum Hall effect state and the interferometer electrodes. The calibrating includes setting a value of a magnetic field across the apparatus such that the reentrant phase and the droplet of the 2D charge carrier gas are present in at least one of the interferometers based on interference measurements on at least one of the interferometers for different values of the magnetic field.
