Quantum Backaction Noise Cancellation for Linear Systems
- Conference date: 19–23 July 2010
- Location: Brisbane, (Australia)
We show that it is always possible to convert a dissipationless linear sensor system under quantum nondemolition measurements into a backaction‐evading one using the technique of quantum noise cancellation. This result generalizes our earlier work on optomechanical sensors [Tsang and Caves, Phys. Rev. Lett. 105, 123601 (2010)].
