Query: Three individual two-axis control of singlet-triplet qubits in a
  micromagnet integrated quantum dot array   We report individual confinement and two-axis qubit operations of two
electron spin qubits in GaAs gate-defined sextuple quantum dot array with
integrated micro-magnet. As a first step toward multiple qubit operations, we
demonstrate coherent manipulations of three singlet-triplet qubits showing
underdamped Larmor and Ramsey oscillations in all double dot sites. We provide
an accurate measure of site site-dependent field gradients and rms electric and
magnetic noise, and we discuss the adequacy of simple rectangular micro-magnet
for practical use in multiple quantum dot arrays. We also discuss current
limitations and possible strategies for realizing simultaneous multi
multi-qubit operations in extended linear arrays.
