Real-time system adapted for communicating with quantum devices

Abstract

A messaging system in a real-time system adapted for communicating with a plurality of quantum devices 207a-207d (e.g. registers of qubits / qudits or coupling devices). The messaging system has one or more aggregator nodes 205, and a plurality of real-time units, communicatively coupled to the quantum devices, as respective leaf nodes 206a-206d. The messaging system is configured to notify a target node 204 of a status of each leaf node in a subset of the leaf nodes. Each aggregator node receives respective notifications from one or more of its child nodes, each notification indicating a status of one or more leaf nodes of the subset of the leaf nodes. Responsive to receipt of the respective notifications from the one or more of its child nodes the aggregator node generates an aggregated notification. The aggregator transmits the aggregated notification to a grandparent node of its child nodes. The grandparent node may be the target node, or it may be descendant of the target node. The messaging system may further be configured to transmit, for concurrent receipt, a message from the target node to each of the leaf nodes in the subset of leaf nodes. Figure 2
