New preprint! Simulating the dynamics of open quantum systems is a major computational bottleneck, largely due to the exponential scaling of density matrices. We're tackling this challenge head-on. In our latest work, we introduce a new method that unravels master equations into quantum trajectories, solved using a stochastic time-dependent variational Monte Carlo approach. What does this mean for researchers? š¹ Drastic reduction in cost: Slashes the computational resources needed for large systems. š¹ Massive parallelism: double Monte Carlo sampling of configurations and of trajectories. š¹ Unprecedented accuracy: Maintains high fidelity even in complex, highly entangled regimes, within the flexibility of the variational approach. This research was driven by the excellent work of Christian Apostoli and Jacopo D'Alberto and our fruitful and always fun collaboration with Marco G. Genoni and Davide Galli. https://lnkd.in/dSr9_idB #OpenQuantumSystems #ComputationalPhysics #ManyBodyPhysics #VariationalMonteCarlo #tVMC #QuantumDynamics #HPC #TheoreticalPhysics #Preprint #arXiv INRiM - Istituto Nazionale di Ricerca Metrologica
