中文摘要	conventional quantum trajectory theory developed in quantum optics is largely based on the physical unravelling of a lindblad-type master equation, which constitutes the theoretical basis of continuous quantum measurement and feedback control. in this work, in the context of continuous quantum measurement and feedback control of a solid-state charge qubit, we present a physical unravelling scheme of a non-lindblad-type master equation. self-consistency and numerical efficiency are well demonstrated. in particular, the control effect is manifested in the detector noise spectrum, and the effect of measurement voltage is discussed.
