Molecular self-assembly based solid-state quantum simulator
Abstract
Quantum simulation is a type of specific-purpose quantum computation that uses one analogous quantum system to emulate the behaviors, of another, often trading controllability for completeness. One most prominent use of quantum simulation is to solve lattice models, of quantum materials with strong electronic correlation - such as the Hubbard model, which is thought to contain highly desired gro,und states like high temperature superconductivity. Established quantum simulation architectures, including trapped ions, Rydberg at,oms, superconducting qubits, optical cavity arrays, are often limited by their scalability or extremely low temperature required to,obtain the simulated ground state. Recent rise of moir? engineering offers a new conceptual route to drastically increase the scalab,ility and accessible effective temperature range, by building artificial lattices from existing lattices. However, their microscopic, interactions are poorly understood, and spectroscopic observables remain limited in these systems. Here we propose to explore condu,ctive metal-organic frameworks self-assembled on functional material substrates as a novel platform for quantum simulation of correl,ated electronic phenomena. Momentum-resolved single particle spectral function will be the observable accessed via angle-resolved ph,otoemission spectroscopy. Taking advantage of the discrete and continuous tunability of the molecule and the caged ion species, symm,etry, packing density, and the substrate s carrier density, we propose to benchmark the experimental tuning methods over a wide port,ion of the parameter space of the simulated Hubbard model, with a specific emphasis on the low effective temperature region and exot,ic lattice symmetries. Compared to typical moir? systems, this platform will come with the added benefit of room-temperature rewrita,bility, scalability and in-situ accessible spectral function in the full momentum space. With this pioneering effort, we anticipate,building and standardizing a new solid state quantum simulator for applications in a broad range of modern condensed matter problems,.Approved for Public Release.
