State evolution formalism
WebHere we give an overview of how the Floquet and Floquet-Markov formalisms can be used for solving time-dependent problems in QuTiP. To introduce the terminology and naming conventions used in QuTiP we first give a brief summary of quantum Floquet theory. Floquet theory for unitary evolution WebA density matrix that represents a valid pure or mixed state must satisfy two conditions: Its trace must be equal to one: Remembering that the trace of a matrix (denoted as Tr) is the sum of its diagonal terms, we have: Tr(ρ) = ∑ k ρkk = …

WebArtificial neural networks (ANNs) for material modeling have received significant interest. We recently reported an adaptation of ANNs based on Boltzmann machine (BM) architectures to an ansatz of the multiconfigurational many-electron wavefunction, denoted as a neural-network quantum state (NQS), for quantum chemistry calculations [Yang et … WebJul 1, 2024 · For large i.i.d. sub-Gaussian A, the approximate message passing (AMP) algorithm is precisely analyzable through a state-evolution (SE) formalism, which furthermore shows that AMP is Bayes optimal in certain regimes. The rigorous SE proof, however, is long and complicated.

WebMar 5, 2024 · The reason is that both formulations describe a state about which we know nothing—we are in a state of total ignorance, the spins are completely random, all directions are equally likely. The density matrix describing such a state cannot depend on the direction we choose for our axes.
