Distinguishing decoherence from alternative quantum theories by dynamical decoupling — •Christian Arenz1, Robin Hillier2, Martin Fraas3, and Daniel Burgarth1 — 1Department of Mathematics, Aberystwyth University, Aberystwyth, UK — 2Department of Mathematics and Statistics, Lancaster University, Lancaster, UK — 3Theoretische Physik, ETH Zürich, Zürich, Switzerland
A longstanding challenge in the foundations of quantum mechanics is the verification of alternative collapse theories despite their mathematical similarity to decoherence. To this end, we suggest a novel method based on dynamical decoupling. Experimental observation of nonzero saturation of the decoupling error in the limit of fast decoupling operations can provide evidence for alternative quantum theories.
