Andras Di Giovanni (Karlsruhe Institute of Technology):
Readout error mitigation experiments on superconducting qubits

In this talk, I will present my PhD research focussed on the mitigation of
readout errors in superconducting qubit devices. I will touch on how
readout errors can arise and why we should care about them. I will
introduce methods based on quantum detector tomography and quantum state
tomography for single- and multi-qubit systems. The two main questions I
will aim to answer are: How can we use detector tomography to better
understand quantum devices and mitigate readout errors? Can we use detector
tomography to find optimal operating parameters for multiplexed readout?
