Quantum nondemolition measurement of a light field component by a feedback compensated beam splitter
Holger F. Hofmann, Takayoshi Kobayashi, Akira Furusawa
In conventional quantum nondemolition measurements, the interaction between signal and probe preserves the measured variable. Alternatively, it is possible to restore the original…

Quantum jumps in backaction evasion measurements of a light field component
Holger F. Hofmann, Takayoshi Kobayashi, Akira Furusawa
Backaction evasion measurements of a quadrature component of the light field vacuum necessarily induce quantum jumps in the photon number. The correlation between measurement resul…
