摘要

We propose a method to emulate the exciton energy transfer (EET) of photosynthetic complexes in a quantum superconducting circuit. Our system is composed of two pairs of superconducting charge qubits coupled to two separated high-Q superconducting transmission line resonators (TLRs), respectively. The two TLRs interact with each other capacitively. When the frequencies of the qubits are largely detuned from those of the TLRs, we simulate the process of EET from the first qubit to the fourth qubit. By tuning the couplings between the qubits and the TLRs, as well as the coupling between the two TLRs, we can modify the effective coupling strengths between the qubits and thus study the geometric effects on the EET. It is shown that a moderately clustered geometry supports optimal EET by using exciton delocalization and an energy matching condition. And the population loss during the EET has been trapped in the two TLRs.
