From a technological standpoint these counterintuitive quantum aspects can be viewed as an unexploited resource that can be harnessed to support various tasks, e.g. in the domains of computation, communication, and metrology..In many applications, however, the potential of nonclassical states cannot practically be exploited due to detection inefficiencies. The authors address this limitation by experimentally realizing a novel detection scheme in which entangling interactions are time reversed. In this way, nonclassical many-particle states are disentangled, allowing them to be detected in a robust and technically feasible manner. In the context of quantum metrology, these nonlinear readout techniques extend the class of entangled probe states that can be leveraged for sensing applications without being limited by finite detector resolution...The authors present an active atom interferometer, where both the entangled state preparation and disentangling readout involve parametric amplification. This “SU(1,1)” interferometer is implemented with the help of spinor Bose–Einstei | | 出版日期 | Book 2018 | | 关键词 | Quantum Metrology; Quantum-Enhanced Interferometry; Atom Interferometry; Active Atom Interferometry; Har | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-96008-1 | | isbn_softcover | 978-3-030-07128-8 | | isbn_ebook | 978-3-319-96008-1Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer Nature Switzerland AG 2018 |
