Entanglement Entropy in Quantum Networks with Tunable Geometry
Andrea Azzali, Sridevi Kuriyattil, Andrew J. Daley +1
Quantum many-body Hamiltonians with two-body interactions can be represented by graphs, with sites as nodes and two-site couplings as edges. We investigate how the geometry of thes…
Variational Learning with Sparse Long-range Entangling Gates
Helene M. Lösl, Aydin Deger, Andrew J. Daley
The performance of variational quantum algorithms depends in general on the structure of the parametrized quantum circuit, but the most common ansätze are typically based on local…
Interaction geometry and ground-state properties of sparse quantum lattice models
Alex Gunning, Sebastian Schmid, Zhengxiao Liu +3
We investigate how interaction geometry shapes the low-energy phases of sparse tunable long-range quantum models. We focus on a class of graphs whose degree grows logarithmically w…
On-site interactions in quantum thermal machines: efficiency, rectification and entanglement beyond local and global master equations
Salvatore Araceli, Teddy H. M. Ong, Baptiste Debecker +4
Advances in experimental techniques have opened new routes for harnessing non-equilibrium dynamics in mesoscopic quantum systems. In this context, we study the impact of on-site in…
Randomised measurements of a disorder-induced entanglement transition in a neutral atom quantum processor
Apollonas S. Matsoukas-Roubeas, Oscar Scholin, Lucas Sá +5
The development and spread of entanglement in complex quantum systems is central to exploring many-body phenomena out of equilibrium. Measuring entanglement dynamics can shed light…
Measurement of Identical Particle Entanglement and the Influence of Antisymmetrisation
Jan Hendrik Becher, Enrico Sindici, Ralf Klemt +3
We explore the relationship between symmetrisation and entanglement through measurements on few-particle systems in a multi-well potential. In particular, considering two or three…
