摘要

In this paper, we study an ultrastrong coupled qubit-cavity system subjected to slow repeated measurements. We demonstrate that, even under a few imperfect measurements, it is possible to detect transitions of the qubit from its free ground state to the excited state. The excitation probability grows exponentially fast in analogy with the quantum anti-Zeno effect. The dynamics and physics described in this paper are accessible to current superconducting circuit technology.
