Use of global interactions in efficient quantum circuit constructions (1707.06356v3)
Published 20 Jul 2017 in quant-ph and cs.ET
Abstract: In this paper we study the ways to use a global entangling operator to efficiently implement circuitry common to a selection of important quantum algorithms. 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.
