    "abstract": "We develop a circuit theory that enables us to analyze quantum measurements\non a two-level system and on a continuous-variable system on an equal footing.\nAs a measurement scheme applicable to both systems, we discuss a swapping state\nmeasurement which exchanges quantum states between the system and the measuring\napparatus before the apparatus meter is read out. This swapping state\nmeasurement has an advantage in gravitational-wave detection over contractive\nstate measurement in that the postmeasurement state of the system can be set to\na prescribed one, regardless of the outcome of the measurement.",
