Our key insight is that knowledge compilation\u2014a technique for efficient repeated inference originating in AI research\u2014can be generalized to work on complex-valued quantum amplitudes, such that the technique serves as the basis for a quantum circuit simulation toolchain geared for variational quantum algorithms.<\/div>\n<div>In knowledge compilation, AI models such as Bayesian networks encode probabilistic knowledge about the world in a factorized format. The Bayesian networks compile down to minimized logical formulas that enable repeated inference and sampling queries with different parameters and new pieces of evidence. The features of the knowledge compilation approach\u2014namely, 1) the ability to represent probabilistic information, 2) the ability to compile probabilistic model structural information into minimized formats, and 3) the ability to efficiently sample from the same model but for varying parameters and evidence\u2014match the requirements for variational quantum algorithm simulation.<\/div>\n<div>Our approach offers performance advantages relative to simulation approaches based on state vectors , density matrices , and tensor networks. The advantages are due to the more compact representation, the circuit minimization and memorization capabilities of our approach, and due to the storage costs for conventional simulators based on matrix representations. The improved simulation performance facilitates studying variational algorithms in the NISQ era of quantum computing.<\/div>\n<div><\/div>\n<p>This is a Virtual Event.<\/p>\n<p>For more information email:<\/p>\n<p>quantumcomputing@ncsu.edu<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Talk Title: Logical Abstractions for Noisy Variational Quantum Algorithm Simulation.
