  Multiplexed operations and extended coherent control over multiple trapping
sites are fundamental requirements for a trapped-ion processor in a large scale
architecture. Here we demonstrate these building blocks using a surface
electrode trap with integrated photonic components which are scalable to larger
numbers of zones. We implement a Ramsey sequence using the integrated light in
two zones, separated by 375 $\mu$m, performing transport of the ion from one
zone to the other in 200 $\mu$s between pulses. In order to achieve low
motional excitation during transport we developed techniques to measure and
mitigate the effect of the exposed dielectric surfaces used to deliver the
integrated light to the ion. We also demonstrate simultaneous control of two
ions in separate zones with low optical crosstalk, and use this to perform
simultaneous spectroscopy to correlate field noise between the two sites. Our
work demonstrates the first transport and coherent multi-zone operations in
integrated photonic ion trap systems, forming the basis for further scaling in
the trapped-ion QCCD architecture.
