Simulating Transmon Lattices for Analysing System Constraints in the Noisy Intermediate Quantum Scale

Thermal noise from electrical circuit components and noise due to fluctuations in energy levels of Transmon circuits have the cumulative effect of decreasing the coherence time of these systems. As coupled Transmon systems scale to the noisy intermediate quantum scale, accurate characterization of noise accumulation and its effects on coherence time and quantum logic gate fidelity is vital. The answer this work aims to provide is the limitations on the coherence time imposed by the noise as the system scales from a few to many (50-100) qubits. The noise analysis is being carried out by a computational simulation of a linear Transmon chain forced into a confinement and surrounded by a bath of thermal photons characteristic of the circuit component radiation. A Generative Artificial Intelligence is used to explore the space of superconducting circuits to develop an understanding of the thermal constraints of a Noisy Intermediate Scale Quantum Computer.
