Round Robin of the European "Metrology for Superconducting Qubits" (MetSuperQ) Project — •Paul Kugler — KIT, Karlsruhe, Deutschland

Project presentation: The MetSuperQ project addresses the urgent need for metrology support in superconducting circuits, a leading technology for practical quantum computers. The qubit round robin aims to enhance qubit coherence times by studying external influences through round robin measurements at multiple institutes and laboratory settings. This initiative will demonstrate qubit readout and benchmarking, disentangle intrinsic from external sources of decoherence, and raise awareness about the reliability of qubit characterization. By closing the gap in metrology support, this project paves the way for fault-tolerant quantum computers and their scalability.
