Quantu m simulation has the potential to be a crucial technique towards solving t his problem. By harnessing the power of quantum information processing\, q uantum simulation can potentially perform tasks deemed intractable by the classical information processing paradigm. In this talk\, I will show that mesoscopic quantum electronic circuit lattices\, built with superconducti ng capacitors and Josephson junctions\, can simulate certain bosonic QFTs in 1+1 space-time dimensions. In contrast to conventional spin-chain latti ce-regularizations\, quantum circuits faithfully capture the non-perturbat ive properties of these QFTs and are experimentally-realizable with modern -day\, superconducting circuit technology. I will begin with the free\, co mpactified boson conformal field theory and analyze its entanglement Hamil tonian for different boundary conditions using analytical and numerical (d ensity matrix renormalization group) techniques. Subsequently\, I will des cribe a quantum circuit lattice for an integrable deformation of the free compactified boson QFT: the quantum sineGordon model. I will present analy tical and numerical computations for the various thermodynamic properties of this model.\n LOCATION:https://researchseminars.org/talk/HEP-TN/4/ END:VEVENT END:VCALENDAR
