Efficient Classical Simulation of the DQC1 Circuit with Zero Discord

Year: 2025

Type: article

Abstract: A path for efficient classical simulation of the DQC1 circuit that estimates the trace of an implementable unitary under the zero discord condition \cite{dakic2010necessary} is presented. 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.
