False vacuum decay in a two-dimensional quantum spin system
Luka Pavešić, 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 Pavešić +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 Reinić, Luka Pavešić, 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 Reinić +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…
Quantum capacitance of a superconducting subgap state in an electrostatically floating dot-island
Filip K. Malinowski, R. K. Rupesh, Luka Pavešić +10
We study a hybrid device defined in an InAs nanowire with an epitaxial Al shell that consists of a quantum dot in contact with a superconducting island. The device is electrically…
Yu-Shiba-Rusinov states, the BCS-BEC crossover, and the exact solution in the flat-band limit
Rok Žitko, Luka Pavešić
We study the subgap Yu-Shiba-Rusinov (YSR) states in the Richardson's model of a superconductor with a magnetic impurity for different electron pairing strengths from the weak-coup…
Qubit based on spin-singlet Yu-Shiba-Rusinov states
Luka Pavešić, Rok Žitko
The local magnetic moment of an interacting quantum dot occupied by a single electron can be screened by binding a Bogoliubov quasiparticle from a nearby superconductor. This gives…
