Scalable quantum state tomography with artificial neural networks The curse of dimensionality and its meaning for NISQ devices The state of a quantum system in its most general form is given by its density matrix $\rho$.

Modern day quantum simulators can prepare a wide variety of quantum states but extracting observables from the resulting "quantum data" often poses a challenge. We tackle this problem by developing a quantum state tomography scheme which relies on …

Time-dependent variational principle for open quantum systems with artificial neural networks Descriptions of Open Quantum Systems (OQS) In a quantum mechanical description, the state of a system is either given by a wave function $\psi$ or the density matrix $\rho$.
