Entanglement for non-adaptive measurement-based quantum computation — •Bülent Demirel1, Weikai Weng1, Christopher Thalacker1, Akshey Kumar1, Matty Hoban2, and Stefanie Barz1 — 1Universität Stuttgart — 2Goldsmiths, University of London
Multipartite entangled states are useful for applications such as quantum networking and computing but also enable intriguing experiments on fundamental questions of quantum physics. Today*s quantum technologies are based on the properties of large ensembles of particles. We show the generation of 4-photon entanglement and test inequalities that correspond to computational games for computing a Boolean function of three bits distributed across four parties - this is all in the non-adaptive measurement-based quantum computation (MBQC) model.*Our inequalities compare quantum with classical where we don*t allow any communication for the classical model or where some limited communication, for a circuit of depth 1, is allowed. We experimentally verify a violation of the inequalities as this demonstrates that quantum can outperform a classical communication circuit.
