False vacuum decay in a two-dimensional quantum spin system
Luka PaveÅ¡iÄ, Ian G. Moss, Simone Montangero
False vacuum decay describes the relaxation of a metastable state through the nucleation and growth of bubbles of the stable phase. Despite describing a broad variety of phenomena…
Resonant false vacuum decay in two dimensions on a 4000-qubit quantum annealer
Gregor Humar, Jean-Yves Desaules, Luka PaveÅ¡iÄ +4
From cosmology to quantum matter, metastable states often decay through the nucleation and growth of competing domains, with false vacuum decay providing the paradigmatic example o…
The Augmented Tree Tensor Network Cookbook
Nora ReiniÄ, Luka PaveÅ¡iÄ, Daniel Jaschke +1
An augmented tree tensor network (aTTN) is a tensor network ansatz constructed by applying a layer of unitary disentanglers to a tree tensor network. The disentanglers absorb a par…
Benchmarking Quantum Red TEA on CPUs, GPUs, and TPUs
Daniel Jaschke, Marco Ballarin, Nora ReiniÄ +2
We benchmark simulations of many-body quantum systems on heterogeneous hardware platforms using CPUs, GPUs, and TPUs. We compare different linear algebra backends, e.g., NumPy vers…
