Progress in low-noise amplifiers, device design, and device calibration has enabled high fidelity readout in transmon qubits. However, challenges arise when scaling up to large numbers of qubits, where deleterious effects such as crosstalk and unwanted interactions can degrade readout fidelity. In this talk, I will discuss how we overcame some of these challenges to achieve simultaneous readout of 53 qubits on Google’s Sycamore processor, enabling the demonstration of quantum supremacy.
