QUBIT CIRCUIT STATE CHANGE CONTROL SYSTEM

摘要

A qubit system is provided wherein successive sets of M RF pulses are generated simultaneously, for application to qubit circuits in a plurality of N groups of M qubit circuits. M switching multiplexer circuits are used, each to pass a respective one of the M RF pulses in the set to a selected one of a plurality of N M to one RF combiners in a multiplexing mode. Combined RF pulses at M different RF frequencies are transmitted from each of the N combiners to a transmission structure for a respective one of the groups. Individual ones of the combined RF pulses are coupled from the transmission structure for the group to respective ones of the qubit circuits of the groups via respective frequency selective filters. In a broadcast mode the M switching multiplexer circuits are used to transmit the simultaneous pulses to all of RF combiners.
