Gauge-fixing quantum density operators at scale
We provide a theory, algorithms, and simulations of nonequilibrium quantum systems using a one-dimensional (1D) completely positive (CP), matrix-product (MP) density-operator (ρ) representation. By generalizing the matrix product state's orthogonality center, to additionally store positive clas...
