CONTROLLING A NETWORK OF DATA PROCESSING DEVICES FOR A QUANTUM COMPUTER

A method for controlling data transmission in a hierarchical network, preferably a star network, of data processing devices, the data processing devices including controllers, e.g. quantum controllers, and a distributor, wherein the method comprises: receiving, by the distributor, a reference clock signal for synchronizing clocks of the data processing devices in the network; synchronizing, by the distributor, a clock of the distributor based on the reference clock signal, so that the clock of the distributor is synchronized with the clocks of the controllers; and, controlling, by the distributor, time-delayed transmission of a data message to at least part of the controllers so that the transmitted data messages simultaneously arrive at the controllers, the time-delayed transmission being based on a delay schedule including information about propagation delays associated with point-to-point connections between the distributor and the controllers.
