Abstract

Is it possible to simulate efficiently using classical means the workings of a quantum computer that used mixed states if no non-classical correlations are generated in the mixed state? We discuss this question in the context of the DQC1 model of quantum computation and sketch path for efficient classical simulation of the DQC1 circuit that estimates the trace of an implementable unitary under the zero quantum discord condition is presented and the challenges in doing such a simulation are elucidated. This result reinforces the status of non-classical correlations quantified by quantum discord and related measures as the key resource enabling exponential speedups in mixed state quantum computation.
