Abstract: Among complex systems with emergent behaviours, frustrated quantum magnets are predicted to exhibit novel, highly nontrivial phases of matter that may play a major role in future and
emerging quantum technologies such as the synthesis of innovative materials for energy harnessing and storage, entanglement-enhanced metrology, and topological quantum computing.
Unfortunately, due to the intrinsic levels of noise in “natural” compounds, the controlled realization, characterization, and manipulation of frustrated quantum magnets appear
exceedingly demanding. On the other hand, we are now entering an advanced stage of development of quantum simulators, engineered quantum systems that realize model
Hamiltonians of increasing complexity in a controlled fashion. Cutting-edge technologies for quantum emulation science include cold atoms in optical lattices, trapped ultracold ions
(Coulomb crystals), NV centres in diamond, and photonic circuits. Taken individually, these approaches present complementary strengths and drawbacks.
By developing, comparing, and assessing them in a comprehensive fashion, project EQuaM’s breakthrough is the controlled experimental emulation of fundamental model Hamiltonians for
frustrated quantum magnetism, both in nontrivial lattice geometries and for competing long-range interactions, and the characterization of their phase diagrams, targeting fundamental
features such as spin liquid phases, global topological order, and fractional excitations. By achieving this objective, EQuaM’s groundbreaking contribution to the long-term vision in
Information and Communication Technologies (ICT) is the efficient quantum emulation, not admitting efficient classical computational counterparts, of many-body quantum systems with
essential elements of complexity. Besides providing crucial insights in the physics of complex many-body systems, it will be a foundational step in the realization of large-scale architectures
for topologically protected quantum computation and information.
