In particular, we focus on the circuits composed with global Ising entangling gates and arbitrary addressable single-qubit gates. We show that under certain circumstances the use of global operations can substantially improve the entangling gate count.</span></p>1 aMaslov, Dmitri1 aNam, Yunseong  uhttp://iopscience.iop.org/article/10.1088/1367-2630/aaa398
