In the double slit experment with a charged particle and a solenoid, there is the shfit of interference patten due to the interaction of the charged particle and the "static" vector potential generated by the solenoid. This intriguing quantum phenomeon is known as the Aharonov-Bohm effect. Here, we predict a new type of the Aharonov-Bohm effect under the influence of a quantum electrodynamic potential. The specific system considered here is a superconducting charge qubit nonlocally interacting with a cavity electromagnetic field. We find that the indirect interaction gives rise to the nonlocal exchange of the two quanta, charge and photon, and leads to remarkable quantum electrodynamic phenomena such as vacuum Rabi splitting and oscillation, and Lamb shift, under the condition that the qubit is located in an electromagnetic-field-free region. | In the double slit experment with a charged particle and a solenoid, there is the shfit of interference patten due to the interaction of the charged particle and the "static" vector potential generated by the solenoid.

In the double slit experment with a charged particle and a solenoid, there is the shfit of interference patten due to the interaction of the charged particle and the "static" vector potential generated by the solenoid. This intriguing quantum phenomeon is known as the Aharonov-Bohm effect. Here, we predict a new type of the Aharonov-Bohm effect under the influence of a quantum electrodynamic potential. The specific system considered here is a superconducting charge qubit nonlocally interacting with a cavity electromagnetic field. We find that the indirect interaction gives rise to the nonlocal exchange of the two quanta, charge and photon, and leads to remarkable quantum electrodynamic phenomena such as vacuum Rabi splitting and oscillation, and Lamb shift, under the condition that the qubit is located in an electromagnetic-field-free region.
Our result can be verified in a realistic experimental setup, and provides a novel approach of investigating the Aharonov-Bohm effect combined with the cavity/circuit quantum electrodynamics.
