Crosstalk remains a major issue in the design of microwave drive lines for fast single qubit control. Microwave drive lines for qubit control must be placed sufficiently far from the qubit to limit the qubit-drive line coupling and the resulting decrease in qubit lifetimes via the purcell effect. However, this generally leads to an increase
Simulations of two qubit gate dynamics have illustrated the well known trade-off between coherent and incoherent errors as a function of gate speed. Faster gates are less susceptible to the incoherent error caused by qubit relaxation, while slower gates have lower levels of coherent error due to unwanted interactions with the non-computational states of the
